SECTION 1 GENERAL INFORMATION Introduction ProScale™ digital measuring systems are affordable precision electronic devices for making linear measurements with speed and accuracy. ProScale consists of a SCALE, a READHEAD (also called ENCODER) and a digital DISPLAY. ProScale uses capacitive encoder technology, the same technology used in digital calipers. Because ProScale is a solid-state electronic device there's very little to wear out.
Product Specifications Measuring Range*: Model 150: 2 Standard Sizes: 0-250mm (10in) and 0-450mm (18in) Model 250: 7 Standard Sizes: 0 to 300mm, 600mm, 1.3m, 2.4m, 3.0m, 3.6m, 6.0m (0 to 12in, 24in, 52in, 96in, 120in, 144in, 240in) Accuracy: + (.025 + .064 x L / 430) mm; max error + 0.20mm @ 1.3 to 6m + (.001 + .0025 x L / 17) in; max error + .008in @ 4 to 20 feet (L = length of measurement in mm or inches) Resolution Reduced: .1mm/.01cm/.01in; Normal: .01mm/.001cm/.001in; Increased: .01mm/.001cm/.
ProScale Terminology All ProScale M150 and M250 systems consist of a SCALE, a READHEAD, (or encoder) and a DISPLAY (digital readout). The SCALE consists of a series of conductive patterns bonded to an aluminum extrusion. The Model 150 Scale is .765 inches (19mm) wide and comes in standard lengths of 14.25 inches (362mm) and 22.25 inches (565mm) to measure 10 inches (250mm) and 18 inches (450mm) respectively. The Model 250 Scale is 2.
each segment the system is absolute. However, crossing over a segment joint now presents the ReadHead with information identical to what it read in the previous segment. At this point the system must be able to recognize that it has crossed a joint and therefore must add or subtract the value of 1 segment: 430mm. In fact, each time the ReadHead passes over a joint it must keep track of how many segments it has passed, and in which direction.
Readheads Absolute Absolute (ABS) style ReadHeads have “BLACK END OF SCALE” labels on the housing cover, and the cable exits from the corner of the housing. Care must be taken not to damage the brass “fingers” inside the ReadHead housing. ABS style ReadHeads, used in all Model 150 and Model 250 systems, must only be used on ABS Scales and with a particular orientation. Each ReadHead has an arrow on the label pointing in the direction of the “BLACK END OF SCALE”.
Displays ProScale Model 150 and 250 measuring Systems can operate with any of several different Displays (sometimes referred to as Digital Readouts). This manual covers the operation of the General Purpose LCD (Liquid Crystal Display) Displays. Other available Displays are mentioned in this section, and other data acquisition accessories are mentioned in Section 6 of this manual. For more information about the available Displays for ProScale Model 150 and 250 Measuring Systems please visit: http://www.
Surface Mount LCD Displays The Surface Mount LCD Displays are an ideal choice for applications where flexibility and easy installation are important. They can be installed with something as simple as Velcro™ or double sided tape, or by using the screw locations inside of the back case or on the outside of the back case. Several versions of this Display are available as described below. Basic Display This Display operates on 2 AA batteries.
Panel Mount LCD Displays The Panel Mount LCD Display for panel and enclosure mounting applications is a perfect choice for manufacturers or OEMs that desire the “built in” appearance for the digital measuring system. This Display comes in three versions, all designed to fit a ¼ DIN (90mm x 90mm, 3.5in x 3.5in) panel opening. Panel Mount, Basic, Battery This Display operates on 2 D batteries. It is ideal for machinery applications where more advanced programming features are not desired or required.
Panel Mount, General Purpose, 24VDC This Display includes all the features of the BASIC 24VDC Display plus it has an auxiliary keypad with 6 keys for switching between ABSolute and INCremental measurements, MONitoring position drift, SENDing data out the SPC connector, HOLDing the reading, and F1 & F2 special function keys. It comes with a connector that allows easy connections for supply voltage and also serves as the output connection for the position Limit / Monitoring output signal.
Other Displays ProScale Model 150 and 250 systems can also be configured with any of the following Displays. Operation of these Displays is covered in their own respective manuals. 1/8 DIN LED Panel Mount Readout: Inches, MM (no fractions) Output: RS485 Output Power: 24VDC Part #: 700-1600-090 http://www.proscale.com/displays/led.
SECTION 2 MODEL 150 & MODEL 250 ProScale Model 150 ProScale Model 150-10 shown with Surface Mount General Purpose LCD Display ProScale Model 150 is a general purpose measuring system with standard measuring ranges of 250mm (10”) or 450mm (18”). Model 150 systems use Absolute (ABS) style Scales, Absolute (ABS) style ReadHeads, and any of several available Displays. This manual covers the operation of the General Purpose LCD Displays with Firmware (F/W) version 2.1 or higher.
1. Note the orientation of the ReadHead on the Scale. Be sure the arrow on the ReadHead points towards the “BLACK END OF SCALE”. This orientation is critical for proper operation. Be sure the mounting location for the ReadHead and Scale will allow this orientation. Take care when sliding the ReadHead onto the Scale so the brass “fingers” inside the ReadHead do not get damaged. (A slight “wiggling” motion when installing the ReadHead will simplify the process.) 2.
5. The Display may be mounted in a location which allows for easy viewing by the operator. The location of all parts should also safeguard the cable from possible damage. ProScale wiring should be kept away from electrical wiring and motors. Plug the ReadHead into the Display. See Section 4: DISPLAY OPERATION. Note: • • If any other mounting method is used, observe the following: Do not drill through the green portion of the Scale at any point over which the ReadHead will travel.
ProScale Model 250 ProScale Model 250 shown with Panel Mount General Purpose LCD Display ProScale Model 250 is a general purpose measuring system with seven standard measuring ranges from 0-300mm (12in.) up to 0-6m (20ft.). Model 250 systems use Absolute (ABS) style Scales, Absolute (ABS) style ReadHeads, and any of several available Displays. This manual covers the operation of the General Purpose LCD Displays with Firmware (F/W) version 2.1 or higher.
1. Note the orientation of the ReadHead on the Scale. Be sure the arrow on the ReadHead points towards the “BLACK END OF SCALE”. This orientation is critical for proper operation. Be sure the mounting location for the ReadHead and Scale will allow this orientation. Take care when sliding the ReadHead onto the Scale so the brass “fingers” inside the ReadHead do not get damaged.

Display Installation Surface Mount Display The SURFACE MOUNT General Purpose Display may be mounted: • Using Velcro or Double sided tape • Drilling out any of the four holes from the inside of the case • Using any of the six holes on the back of the case which may tapped for M2 or 4-40 screws. NOTE: Care must be taken when using the inside holes. If using the lower left hole as shown above, be sure to use a screw that will not rise above the extruded countersink as this may short the input connector.
SECTION 3 CALIBRATION/MAINTENANCE Calibration The accuracy of the ProScale system is dependent on the manufacturing of the Scale. Since the Scale is passive, there are no calibration adjustments available or necessary. The Displays have a built-in “scaling factor” that allows correction for slight linear inaccuracies that may be observed once ProScale has been installed in your application. Refer to Section 4: PROGRAMMING (Programming Parameter Pr7) and Section 5: ABBE ERROR.
Compensation Calibration This example uses 5 inch measurement standards and an Accurate Technology ProTable as the measuring system under calibration. Other applications and different length measurement standards would be similar. To program the compensation table into the ProScale Display, (firmware version must end in C), complete the following steps: 1.
To disable compensation mode, change Pr 27 to 0. This does not erase the compensation table stored in memory. Changing Pr 27 to 1 will re-enable the previously stored compensation. Note: Defaulting the display back to factory settings does not erase the compensation table. (See Section 4: THE LCD) Maintenance ProScales will operate in a dry environment with non-conductive debris such as sawdust, plastic, dust, etc with no adverse effects. The system should be cleaned of excess debris when necessary.
Changing the Batteries A low battery indicator will appear in the lower left corner of the LCD Display when new batteries are needed. Press and Hold ON/OFF key for 5 seconds to Display Battery Voltage. Surface Mount Displays: Remove the screws in the upper right and lower left corners. Pull the cover off. Remove the old batteries. Reinstall 2 new AA Alkaline batteries, noting the proper orientation. Replace the cover and tighten the screws.
SECTION 4 DISPLAY OPERATION This section covers the programming and operation of ProScale Surface Mount and Panel Mount LCD Displays Firmware* V2.1 and higher. If your Display Firmware is prior to 2.1, or your Display is different than the Displays described here, you must use the appropriate user manual for that Display. * (F/W version is displayed on power-up or when ON/OFF key is pressed.) The LCD The above figure illustrates all the segments available on the Display.
To enter PROGRAMMING MODE, press and hold the MODE key and then momentarily press the 0 (zero) key. The MODE key must be held for approximately 1 second before the depression of the 0 (zero) key. Once you are in the Programming Mode, momentarily pressing the MODE key will advance through the Programming Parameter list. To step backwards in the Programming Parameter list press and hold the ON/OFF key and momentarily press the MODE key.
Pr0 – Reading Direction [0,1] Change/Reverse the direction (+ vs -) of readings. Pr1 – Enable/Disable Segment Offset 0 = For ALL Incremental Scales 1 = For All ABSOLUTE Scales [0, 1] Pr2 – High Speed ReadHead [0, 1] 0 = Normal ReadHead 1 = High Speed ReadHead Use only if instructed. A setting of 1 will impact battery life. Pr3 – Enable/Disable the +, - and ZERO keys [0,1] 0 = Disables operation of Zero, + and – keys (Forced Lock Mode). 1 = Enables operation of Zero, + and – keys.
Pr8 – Automatic Power Off [0 to 60] Default = 15 Sets the amount of time in ‘minutes without activity’ before the Display automatically turns off. 0 = Disables Automatic Power Off. ReadHead motion or ON/OFF key will “wake-up” the Display and reset the timer. Pr9 – Auxiliary Keys Enable/Disable [0..7] 0 = ABS/INC, MON and HOLD Disabled 1 = ABS/INC Key Enabled 2 = MON Key Enabled 4 = HOLD Key Enabled 7 = All Keys Enabled To enable keys, add up combination of key values. A value of 2 enables only the MON key.
Pr14 – Output Signal Mode [0, 1, 2] Configures the hardware output signal for activation on MONitor drift conditions or Upper/Lower limit alarm conditions. Applies to 24VDC Displays only. SEE Pr15, Pr16, Pr17 ALSO 0 = Off 1 = Monitor Drift 2 = Upper/Lower Limit Pr15 – Output Polarity [0, 1] Used to configure the signal output. N/O or N/C in relation to circuit ground. 0 = N/O, the output is Normally Open (not conducting to ground). 1 = N/C, the output is Normally Closed (conducting to ground).
Pr22 – Backlight ON time [0, 1, 2, 3 or 4] The ON time of the LCD backlighting (24VDC Displays only). 0 = always off. 1 = 3 seconds. 2 = 7 seconds. 3 = 15 seconds. 4 = always on. NOTE: Backlighting is activated when a key is pressed. Pr 23 Future Use DO NOT CHANGE [1] Pr 24 Display RF Address [0 to 63] This parameter is used to set the address of the Display. 0= (RF off) Pr 25 RF System ID [0 to 31] This parameter is used to set the ID of the Display system (or family). Pr 26 Noise Suppresion [0..
Primary Key Functions ON/OFF Momentarily pressing the ON/OFF key will cause the Display to turn on or off. The Firmware Version is momentarily displayed on power-up. While on, if no key presses or positional changes occur within 15 minutes*, the Display will automatically turn itself off to conserve battery life. While off, if a position change is detected (larger than .05mm or .002in), the Display will automatically turn itself on with no loss of measurement information.
+, 0, and – Keys The + (plus), 0 (zero) and – (minus) keys are used to change the currently displayed position to a different value. The 0 key forces the unit to display 0. Momentarily depressing the + key increments the current position by one unit of measurement. Momentarily depressing the – key decrements the current position by one unit. Pressing and holding the + or – keys will cause the displayed position to change continuously. Holding down the key will cause the amount of change to speed up.
position of the ReadHead. This is typically a position of zero (0) but may be changed by using the + or - keys to provide an offset. Moving the ReadHead in either direction will display the distance moved from the initial INC starting point (plus any offset). To complete another incremental measurement from the new position, momentarily press the ABS/INC key. The Display will again change to 0 (or the previously programmed offset).
SEND The Display (except BASIC Models) provides an output port that can be used to send measurement information to a compatible SPC device such as a printer or data acquisition unit. After connecting the SPC device to the 10 pin connector on the Display, the user may initiate the data transmission by momentarily pressing the SEND key. This signals the SPC device to acquire the data from the Display.
Display Functions Lock Mode The user can “lock-out” the position offset adjustment functions (+, 0, - keys) to prevent accidental changes of the current displayed position. To activate the lock mode, press and hold the ON/OFF key and then momentarily press the MODE key. The word LOCK on the LCD Display will turn on or off with each lock/unlock operation. When the LOCK symbol is displayed, the +, 0, and - keys will be inactive.
Limit Mode The Display will show either “LL“ for Lower Limit or ”UL” for Upper Limit if a pre-programmed upper or lower reading is encountered. Upper and Lower Limits are set with Programming Parameters Pr16 and Pr17 but are only active if Pr14 is set to 2. The readout toggles for 2 seconds between current position display and "LL" or "UL". This continues as long as limit is exceeded. (Programming Parameters 14, 16, 17) Caution: Limit monitoring is always active, even in programming mode.
24VDC Display Operation The 24VDC Displays have some additional functions that are not available on battery powered Displays. The same connector that is used for power is also used for the output signals. See below: 24VDC Displays are designed to run on DC voltage ONLY.
Jumpers Surface Mount Displays Although the ProScale Display uses a keyboard-programming method to enable and configure features in the unit, several selection jumpers are located on the circuit board for additional system configuration. User configurable jumpers consist of three pins and a ‘shorting block’. The center of these pins is ‘Common’. One end pin is labeled ‘A’ and the other end pin is labeled ‘B’.
Panel Mount Displays JP3 JP4 Panel Mount Display Circuit Board JP1 JP2 JP1 & JP2 Display Power These jumpers set the Display to operate on either 2 D batteries or 24VDC. To configure the Display to operate on 24VDC power JP1 AND JP2 should be set to position A. THEY MUST BE SET ON THE SAME SETTING TO AVOID DAMAGE To configure the Display to operate on battery power JP1 AND JP2 should be set to Position B.

Key Press Function Summary How long a key is depressed, and the combination of the keys pressed is important. The term (Momentarily) describes a key press of typically less than 1 second. Whereas (Press & Hold) is used to imply a key press of typically longer than 1.5 seconds. For example: When using a PC keyboard to type a CAPITAL letter you would “press and hold” the SHIFT key and “momentarily” depress the LETTER key.
SECTION 5 MISCELLANEOUS Frequently Asked Questions What does “no Enc” mean? If the ReadHead is off the Scale, or the ReadHead cable is unplugged from the Display, a “no Enc” will appear on the Display. To clear error: 1. Be sure the ReadHead is on the Scale and properly oriented. 2. Unplug the connector from the Display for one second. 3. Reconnect the ReadHead cable to the Display. The battery clips seem to be very loose.
