GMC-I Messtechnik GmbH DP Pro DIGITAL PRESSURE METERS The Model DP pro is a family of microprocessor-based, high-precision Pressure Meters, which are intended for use in the evaluation and servicing of a wide variety of medical, commercial and industrial applications. These meters measure compatible gas and liquid pressures in various engineering units.

LAYOUT This section looks at the layout of the DP Pro and gives descriptions of the elements that are present. Pressure Port #2: Male Luer coupler pictured Analog Output: BNC (Optional) Temperature: ¼” Phone Jack (Optional) NOTE: Coupler type depends on sensor and options, see Model Information for details. Pressure Port #1: Female QuickDisconnect pictured NOTE: Coupler type depends on sensor and options, see Model Information for details.
SCREENS MAIN SCREENS – There can be up to four main screens, depending on the model. They are PRESSURE 1, PRESSURE 2, TEMPERATURE, COMBINED and INPUTS. The available screens can be toggled through using .
Input Identification Screen Note: Sensor limits are displayed based on selected range. PRESSURE SCALE – The pressure scale is indicated by the units displayed under the reading. The scale can be changed by using to highlight the unit line and to toggle between available pressure units as listed below.
TEMPERATURE SCALE – The temperature scale is indicated by the units displayed under the reading. The scale can be changed by using to highlight the unit line and to toggle the temperature units between Degrees Celsius (°C) and Fahrenheit (°F). NOTE: If the measured temperature is outside of the range of the instrument, an OVER RANGE or UNDER RANGE message box will be displayed. For models with the YSI option, the NO PROBE message box will be displayed when the unit detects an open connection.
The following is a breakdown of the parameters available in the configuration of the unit and their available options: System Setup Configuration Parameter Display Min/Max Analog Scale Description Selects whether the Min and Max values will be displayed on the main screens (except COMBINED). Analog Output Scaling voltage. This is the maximum analog output voltage. The output is scaled to this voltage over the positive range of the selected analog source.
ZEROING PRESSURE SCALES – When there is no pressure applied to either port, the display should read “0.” It may be necessary to zero the pressure scales to remove any errors due to ambient conditions. This is done by pressing the zeroing instructions are displayed, then pressing key until the simultaneously to begin the process. The “ZEROING…” message will flash while the scale is being zeroed. When the zeroing instructions are displayed again, the process is complete.
KEYS Six tactile-touch keys are provided for system operation: – This key turns the unit off and on. The unit will return to the main screen that was active when it was turned off. – In the DISPLAY MODE, these keys toggle the display through the available main screens. In the SELECT MODE, if a parameter has been highlighted, these keys will scroll through the available settings. – On any screen, there are a number of parameters that may be selected and changed.
– This key toggles the unit into and out of the Setup Mode. Depressing this key will enter the Setup screen where the configuration can be viewed and adjusted. Depressing the key again will exit the Setup Mode and return to the previously viewed main screen. This will also save any changes to the internal EEPROM memory so they will be retained even with the power turned off or battery removed.
OPTIONS ANALOG OUTPUT – The unit may be ordered with a DC Analog Output Option. This option provides a filtered analog output that is representative of the displayed pressure or temperature, and is provided via a BNC connector on the top of the unit. The source parameter for the analog output is selectable in the Setup Menu between Pressure (Pres) or Temperature (Temp). The output is scaled to match the 0 to FS range of the selected source parameter over a variable internally generated reference voltage.
COMMUNICATIONS Since the meter does not handle a great deal of data, the RS-232 communications link has been optimized to allow the user, through very simple instructions, to control and request data from the meter. Refer to Specifications section for RS-232 Settings (Baud, etc). Data transmitted/received is in standard ASCII format, and all numerical values are in BCD format. All commands sent to the unit should be terminated with a “Carriage Return” character ( or in hexadecimal, 0x0D).
Examples: Data Sent W064 Data Returned W064 W0600004 W0600004 W05100 ?? U - UPLOAD Meaning Echo of Command Sent (Set Pressure units to “inH2O”) Echo of Command Sent (Set Pressure units to “inH2O”) W05100 Echo of Command Sent Invalid Command Response (Location 05 is Read Only) The UPLOAD command allows the user to read all of the selected device data from locations 1 through 16 with a single command.
X - CANCEL The CANCEL command is simply a way to re-establish proper control, should a communications error occur or an incorrect command be transmitted. For the most part, an incorrect command will simply be ignored and the meter will return to listening for future commands. However, a prior command may be cancelled midstream by transmitting the CANCEL command anytime. Usage: X This command does not require a carriage return, nor will it acknowledge with a carriage return.
