HMG 3000 Seite 4 1 Tasks and Functions of the HMG 3000 The HMG 3000 portable data recorder is a hand-held unit for simple measurement and data capturing tasks involving hydraulic and pneumatic systems. Applications extend primarily to maintenance and servicing, troubleshooting and test rigs. The HMG 3000 can concurrently evaluate signals from up to 10 sensors.
HMG 3000 Seite 5 One special feature of the HMG 3000 is its ability to record measurements of the highly dynamic processes in a machine. To this end, two input channels are featured which are capable of recording measured values at a rate of 0.1 ms. It goes without saying that this feature is dependent on the use of suitable, fast-acting sensors.

Select the desired format, followed by entering the current date and time via the keypad. Save your entries via OK, followed by pressing Continue.
HMG 3000 Seite 12 Extras — menu featuring the stopwatch, among other things plus a function for displaying the Min/Max values. Special significance is accorded the measurement of the Min/Max values, which is why it is explained in detail below. Apart from the current measured values, the HMG captures the minimum and maximum values (Min/Max values) too, except when recording a measurement curve.
HMG 3000 Seite 13 5 Getting Started Guide This Getting Started Guide outlines the basic steps for conducting a simple measurement (measured values shown in display) and recording a measurement curve (graph of measured values). These examples involve pressure measurement using 2 pressure transmitters with sensor detection (HSI sensors). For a detailed description of all the settings, see Detailed Operating Instructions. The examples are based on the factory settings of the HMG 3000.
HMG 3000 Page 14 When HSI sensors featuring automatic sensor detection are used, the HMG automatically detects the measurement range and the unit of measurement of the two connected pressure transmitters and shows them in the display with the current measured values. You can also have the minimum and maximum values for the sensors displayed. To hide or unhide the Min/Max display, actuate the right arrow of the 5-way navigation key until Min/Max is highlighted in blue and then press the OK key.
HMG 3000 Page 15 The HMG now shows the measured values in the 7-segment display panes. Depending on the setting, the Min/Max values are shown in addition to the current measured values. The Recording menu is used for recording measurement curves. During recording, the measured values are recorded for a certain period of time, stored and then shown as a graph. Example of Recording a Measurement Curve: The function bar of the Current Measured Values menu contains the item Recording.
HMG 3000 Page 16 In the Recording option line, select End when time has elapsed in the same manner. Your screen now shows the settings for recording measured values made by you (cf. screenshot at right). To double-check your settings, refer to the recorded data selected by you above the function bar. Now you can start recording via Start in the function bar + OK. A progress bar shows you the status of your measurement.
HMG 3000 Page 17 6 Detailed Operating Instructions 6.1 Settings Menu Submenus of the Settings menu: • • • • • • Change settings of measurement channels Change display settings Zero measurement channels Change initial setup Administer settings (save, load, ...) Administer sensor configuration (not visible unless the configuration of a SMART sensor has been read out, see section 6.4.2.5) 6.1.
HMG 3000 Page 18 In the Mode menu you now have the option of Automatic detection (HSI) and Manual. The Automatic detection (HSI) option is used for HYDAC sensors featuring automatic sensor detection. The Manual setting is used for adapting sensors featuring standard analog signals to the HMG (e.g. 4-20 mA). However, there are applications in which entering settings by hand is useful, also for HSI sensors.
HMG 3000 Page 19 A drop-down list is also provided for selecting the Unit (of measurement). You also have the option of defining your “other unit” (uppermost line of the drop-down list). The cursor then jumps to the input box and a small triangular arrow appears as the insertion point. Enter the new unit using the combination keypad, e.g. ”kPa” for kilopascal. To enter additional characters, move the triangle insertion point to the desired position and enter the characters.
HMG 3000 Page 20 Example: For both 100 bar pressure transmitters there is a differential measurement range of -10 – +10 bar, in other words a measurement margin of 20 bar. The accuracy of ≤±0.1% refers to this measurement margin. The pressure differential can therefore be measured with an accuracy of ≤±0.02 bar. To measure a pressure differential, select the item Pressure differential dP. Then you find an item Organise curves. Here you can plot up to 3 curves for 3 pressure transmitter pairs.
HMG 3000 Page 21 Connect the pressure transmitter hydraulically so that the two instruments are subjected to the same pressure. The ideal for recording curves is connecting to a test rig on which you can increase the pressure slowly from 0 bar to the full measurement range of the pressure transmitter and back again. However, the minimum requirement is to record the curves/measured values in the pressure range in which the differential measurement is to take place later.
HMG 3000 Page 22 In order to measure the flow rate using a differential pressure measurement at a flow rate orifice, select the item Orifice measurement Q=f(dP). Then select the number of decimal places and the unit (of measurement). A flow rate orifice is supplied with information showing the correlation between pressure differential and flow rate. For example, on a HYDAC EVS 1000 it says: calibration factor 4.87 bar at 350 l/min. Enter these values under the flow rate and pressure.
HMG 3000 Page 23 Input channels I and J are for digital signals. As the input signal you can choose between Count pulses and Frequency signal. There are many possibilities for this, e.g. speed sensors, proximity switches, pulse generators, flow rate measuring instruments with a frequency signal, HYDAC HDS 1000, to name only a few. As in the case of the analog sensor inputs, settings can be manually entered for the input signal, unit of measurement and decimal format.
HMG 3000 Page 24 Examples of frequency measurement: 1) You would like to measure a frequency up to 1000 Hz. Frequencies are recorded by the HMG per minute. Enter "60" as the Factor to display the frequency in Hz, enter "1000" for the Upper measurem. range to scale the Yaxis from 0 to 1000 in the graphical display. 2) You would like to measure the speed of a machine from 0 to 2900 rpm, the speed sensor supplies 2 pulses per revolution. Enter "2" as the Factor and "3000" as the Upper measurem. range.
HMG 3000 Page 25 If you have selected counter pulses as the input signal, and have returned to the normal measurement value display, you will find on the far right of the function bar a symbol, as shown in the screenshot. The counter is currently stopped. If you select the symbol using the arrow key and confirm with OK, the counter is reset and will start again. To stop it, select the symbol again using the arrow keys and confirm again with OK.
HMG 3000 Page 26 You should set this value as close as possible to the expected power value to get the best possible graphical display. If measured values exist which are larger than the upper measurement range, these are not lost. The scale of the Y-axis can be changed again in the graph at any time later on. This brings you back again to the display shown on the right. In the example, a power is shown at channel K, and the difference at channel L.
HMG 3000 Page 27 6.1.2 Changing Display Settings The next submenu of the Change Display Settings item enables you to make settings affecting the display and rendering of measured values and the display size in keeping with your measurement task. Select the item using the arrow keys, followed by OK. When selecting Measured value display, a drop-down list appears enabling you to choose the rendering speed: • • • • Fast Medium Slow Delayed Make your selection, followed by pressing OK.
HMG 3000 Page 28 The screenshots at the right show the measured values of four sensors when selecting the 2 display panels rendering option and activating Min/Max display. Consequently, the display only shows the measured values of two sensors at a time. The arrow keys ( ↑ ) and ( ↓ ) enable you to access the measured values of the other two sensors. In order to display the measured values of 4 sensors simultaneously, you need to select the 2x2 display panels option (cf. screenshot).
HMG 3000 Page 29 6.1.3 Zeroing Measurement Channels You can rezero the measurement channels in the Settings menu. This function is used to mask out backpressure buildups present in the system. For example, if a pressure of 3 bar is present at a pressure transmitter despite the facility having been switched off, this value can be used as the new zero point for display purposes. Rezeroing can be done at any point throughout the measurement range of a measurement channel.
HMG 3000 Page 30 Switching the HMG unit or measurement channels OFF/ON doesn't automatically cause the newly set zero point to be deleted. The following message is shown when switching the HMG off and then back on: "Some channels have a zero offset." Press OK to retain the zero offset or Esc to delete it. To determine the extent of a zero offset which has been set, go to the Settings menu and select Zero measurement channels. You are shown a list of all the channels which are active.
HMG 3000 Page 31 6.1.4 Changing the Initial Setup The Change initial setup item is a submenu of the Settings menu. To make changes to the initial setup, press OK. You can now change the following items: Language You can choose between German, English and French. Select your language using the arrow keys, followed by OK. Setting/Correcting the Date and Time Various format options are offered depending on the language selected by you and the associated regional formatting applicable to the date and time.
HMG 3000 Page 32 Note: Automatic conversion of measured values to the selected unit of measurement doesn't work unless Automatic detection (HSI) mode is selected under Settings – Measurement Channel Settings. Select the unit of measurement to be changed, followed by OK. Select the new unit of measurement desired from the dropdown list via OK. In the list of measurement channels, the measurement range for this channel is now shown in 0 – 1450 psi instead of in 0 – 100 bar, for example.
HMG 3000 Page 33 6.1.5 Administer settings (save, load, ...) All of the measurement channel settings made by you in the HMG for the last measurement can be saved and then reloaded later on for the purpose of periodically repeating the same measurement, for example. You can also delete individual stored settings or restore the factory settings. Select Administer settings (save, load, ...), press OK, and now proceed to the Administer Settings menu with its four submenus (see screenshot).
HMG 3000 Page 34 In the submenus Load stored settings or Delete stored Settings, you are shown a list of all the saved settings from which you can Load or Delete individual settings. Navigate to a setting using the arrow keys and confirm via OK. The item "activated" in the function bar jumps, enabling you to accordingly Load or Delete the setting. You can restore your HMG to the original setup present when delivered by selecting Restore factory settings.
HMG 3000 Page 35 6.2 Recording Menu Here the HMG enables you to perform a measurement for a specific period of time and save it. This recording can be rendered as a graph or a table. To do this, proceed as follows: To access the recording menu, go to the Current Measured Values menu, then select Recording in the function bar at the bottom. In the Recording menu that follows, select Start recording, View recording or Delete recordings, and confirm via OK. 6.2.
HMG 3000 Page 36 Sampling rate This item enables you to set the rate at which the HMG reads a measured value from the sensors and stores it in the internal memory. A measurement curve may comprise up to 500,000 measured values. Selecting 1 ms, for example, means that 1000 measured values per second are taken and stored for each connected measurement channel. Use the arrow keys ( ↑ ) and ( ↓ ) to scroll through the various settings for the sampling rate.
HMG 3000 Page 37 The sampling rate which can be set is also dependent on the active measurement channels: • 0.1 ms • 0.2 ms • • 0.5 ms 1.0 ms max. 2 analog input channels max. 4 analog input channels all 10 input channels for SMART sensors Recording time A drop-down list appears when this item is selected. Using the arrow keys (↑) and (↓) you can select a recording time of between 1 second and 24 hours, followed by pressing OK.
HMG 3000 Page 38 Example of Recording a Simple Measurement Curve The settings made for the example shown at the right mean that the measured values of channels A and B are captured with a sampling rate of 1 ms (i.e. 1000 measured values per second, referred to as data records (recorded data)), and that recording is automatically discontinued after 10 seconds.
HMG 3000 Page 39 Before doing this, you can have the measurement shown again as a curve (Graph + OK) or as a measured value table (Table + OK). When doing this, other tools are offered for analyzing the chart or table. For more information on how you can retrieve recordings and view them as a curve or table, please refer to Viewing Recordings. Back/Esc enables you to return to the Simple Measurement Curve Recording – Status screen. To store the recording, select Save and confirm via OK.
HMG 3000 Page 40 Measurement Curve with Trigger Measurement curve with trigger is another recording option. "Trigger" means that a measurement curve can be started automatically when one or more specific events occur. Events can be a limit being exceeded or fallen short of or a measurement window being departed from.
HMG 3000 Page 41 Event: Actuation of button/key The simplest event is actuating a button or key to trigger a measured value recording. After starting the recording, you can trigger measurement by selecting Trigger in the function bar (+ OK). Event: External signal change An external signal change means that you apply a direct current signal to one of the frequency inputs (I or J), e.g. via a button (NC or NO contact).
HMG 3000 Page 42 Event: Leaving measurement window This trigger event is very similar to Specific value. You can specify a Lower Limit and an Upper Limit. The trigger is activated when the measured value enters the measurement window. However, recording is not started until the measured value leaves the measurement window in a rising or falling direction. Event: Timed The event setting using a time function ("timed") is useful for measurements which are to be repeated at specific intervals.
HMG 3000 Page 43 Linking Events You also have the option of linking events. Without linking, each of the four events acts alone and independently as a trigger for a measurement recording. In the line Joint events (options shown to the right) a drop-down list opens containing the linked event options.
HMG 3000 Page 44 The next setting parameter for recording a triggered measurement curve is Pre/post trigger. After starting a triggered measurement curve the HMG begins to record the measured values for the recording time set (e.g. 30 seconds). If the trigger event does not occur during this time, the oldest measured values are replaced with new measured values in the measured value memory. This means that you always have the set recording time as the "past" in the measured value memory.
HMG 3000 Page 45 Example of an Automatically Triggered Measurement The following occur in a hydraulic press from time to time: defective components, ruptured hoses or cracked cylinders. You suspect there may be extremely high pressure peaking in three hydraulic circuits and want to monitor the press for pressure surges for an extended period of time.
HMG 3000 Page 46 As soon as you confirm saving via OK, measurement is activated, resulting in the screen shown at the left. Selecting Graph causes a measurement curve to be plotted and displayed (cf. top screenshot), selecting Measured values causes you to proceed to the normal measured values screen (cf. bottom screenshot). If you like, you can switch back and forth between the Status, Graph and Measured values screens.
HMG 3000 Page 47 Event Log The Event Log option enables you to store measured values as a table. A line in the table contains the current measured value, in addition to the Min and Max value of each active channel. The trigger settings enable you to specify which event is to create a new line in the event log once the measurement has been started (e.g. Actuation of button/key, Specific value). As soon as a new measured value line is saved, the Min and Max values are always automatically reset.
HMG 3000 Page 48 • In order to also manually generate a measured value line, set a second event to Actuation of button/key. • Automatic measurement: Deactivated Upon starting measurement, a new menu window Event Log Recording — Status opens, enabling you to track the measurement on the basis of the settings. Data is recorded only when an event occurs. The sampling rate for the event log is automatically determined by the HMG in keeping with the number of active measurement channels: • 0.1 ms max.
HMG 3000 Page 49 Using the arrow keys of the 5-way navkey, you can select the arrows next to the scroll bar. After confirming via OK, you can scroll in the table up/down and left/right. A single arrow means scrolling line by line, a double arrow means screen by screen, and means "jump to the beginning or end of the table". You can discontinue recording the event log via Stop in the function bar.
HMG 3000 Page 50 The Comment item enables you to enter a text, e.g. a description indicating the operational status of the unit or facility while the recording was being made. The HMG saves the measurement settings together with each recording so that a detailed measurement log is created. Note: For the same example, if you select automatic measurement Activated and start the measurement with Start, you are asked to allocate a Name and a Number to the measurement.
HMG 3000 Page 51 6.2.2 Viewing Recordings The View recording item in the Recording menu causes a list of the recordings stored in the HMG to be displayed. Use the arrow keys to select the measurement you wish to view. The selected recording is indicated by an arrowhead and is blue-highlighted. The associated recorded data appears above the function bar.
HMG 3000 Page 52 Graph A measurement can also be rendered as a measurement curve. To do this, select Graph + OK in the function bar. The screenshot at the right shows what appears next in your display. The measurement is scaled throughout the entire time range (x-axis) and measurement range (y-axis). Above the y-axis you can see which channel is currently scaled along the y-axis.
HMG 3000 Page 53 Back Back/Esc enables you to return to the previous menu. Automatic: Automatic causes all individual curves to be optimally rendered "automatically". When selecting Automatic (+ OK) the y-scaling is automatically adapted for each active channel separately, i.e. the y-scaling is zoomed to its maximum size. Navigate: Navigate is used for the quick precisionevaluation of a measurement curve or rendering of parts thereof.
HMG 3000 Page 54 Use the ► and ▲ arrow keys while holding the Shift key down to enlarge a portion of the measurement in the x- or y-axis. Use the ◄ and ▼ arrow keys while holding the Shift key down to decrease or "squash" the curve in the x- or y-axis. (cf. screenshot) Magnifier: To explore a section of the curve and zoom it, use the Magnifier (+ OK). The function bar contains similar functions for shifting and resizing as the Navigate feature does (see previous page).
HMG 3000 Page 55 Ruler: When the Ruler is activated, the screen takes on an appearance as shown in the screenshot. The function bar contains the commands which can be accessed for the ruler. Using the arrow keys by themselves enables you to determine the pressure at a particular point in time.
HMG 3000 Tracker: Using the Tracker is similar to using the ruler. The difference is that each value actually measured is rendered by a point. Only a ruler appears for "processing" the curve through time. The tracker "jumps" from one measurement point to the next, with the respective measured value of each measurement channel shown along the y-axis to this point x in time (x-axis).
HMG 3000 Page 57 Display all: Display all causes the recording throughout the entire recording period to be rendered with all the measured values. This option is used to restore the point of departure of a recording. Display All + OK causes the measurement throughout the entire time period to be restored along with the complete measurement range scaling if the ranges had been previously limited. Settings: Settings causes the measurement channels to be shown which have been used to make the recording.
HMG 3000 Page 58 In the list of channels, select a channel to the right next to the box, and confirm via OK. In the next menu you see an overview of the measurement range, current scaling (upper and lower limit) of the y-axis, line style and colour in which the measured values of this sensor is shown. You can reset all the parameter settings except for the measurement range. The default scaling (upper and lower limit) can be manually changed here via the keypad.
HMG 3000 Page 59 Entering the following new settings for "Sensor measurement 3(1)" would result in the curve shown at the right: Scaling (lower and upper limit) of y-axis: 0 - 100 bar – Control line Time range of x-axis: 3.00 – 5.00 s – Time Info: The last item Info in the graph screen is used to view and modify comments entered by you (comments are entered using the combination keypad). You can also have the recording data for a measurement displayed. To exit the Info menu, use Back.
HMG 3000 Page 60 Table Tables are useful for displaying individual measured values. Select Table (+ OK) in the function bar to select a stored recording shown and have its values displayed. For a simple measurement curve recording you are shown a measured values table listing the measured values of the active channels in columns and the associated recording time in rows. No Min/Max values are shown here as they are not captured while recording the measurement curve.
HMG 3000 Page 61 The date and Min/Max values can be hidden so as to make tables easier to read. You can hide and unhide Min/Max and the Date via OK. You can also hide and unhide individual channels for display in the table using the Settings function (a checkmark means that the channel is displayed; hide/unhide via OK). You can also jump to a specific place in the table via the date and time setting in the column next to the beginning of the table.
HMG 3000 Page 62 6.2.3 Deleting Recordings Any recording can be deleted when no longer needed. To do this, select Delete recording in the Recording menu + OK: you are now shown a list of all the stored recordings. Now select the recording to be deleted. A small arrowhead to the left of the file name shows you what you have selected. Before selecting a recording, you can sort the list by • Name • Number • Recording started and in ascending (↑) or descending order (↓) in each case.
HMG 3000 Page 63 6.3 Extras Menu The following options are available to you in the function bar of the Extras menu: • Stopwatch The stopwatch offers you the following functions: Start, Stop, Interim reading and Reset. • About HMG 3000 • SMART sensors • Update Instrument Software.
