    SETUP MODE The Setup Mode allows the user to adjust the configuration of the meter. The Setup Mode is entered by pressing The ON/SETUP key when the unit is on. The parameter and the current value will alternately flash in the display. The following table indicates the Parameters that are available, their meaning and available setting range: PARAMETER DESCRIPTION...
  • Page 14: Inputs

    INPUTS PRESSURE INPUT – Male luer lock connector is used for the pressure input. POWER INPUT – A 2.5 mm jack is provided for the optional 9 VDC power supply that may be used for continuous run applications. It bypasses the internal battery when plugged in. RS232 –...
  • Page 15: Calibration Mode

    CALIBRATION MODE A special mode has been included in the unit to provide the ability to calibrate the instrument as well as set advanced Parameters. The Calibration Mode is entered by depressing both the SETUP and UP keys simultaneously while in the Setup Mode. After matching the access code, the first parameter and the current value will alternately flash in the display.
  • Page 16 In addition to viewing the parameters for the pressure and temperature calibration, they may also be modified. This is the digital calibration process. The following is a procedure for calibrating the instrument. Only a qualified service technician should perform this function. The steps start from the main display and detail how to enter the calibration mode and then how to instruct the unit to update its calibration registers.
  • Page 17 TEMPERATURE CALIBRATION (MODEL DPM-1300 ONLY) 1) Enter the Setup Mode by pressing the SETUP key. 2) Press and hold the SETUP key. 3) While keeping the SETUP key held down, press and hold the UP key for 5 seconds. 4) The display should change to ‘CodE’. Release the SETUP and UP keys. 5) Input the Calibration Code using the UP and DOWN keys.
  • Page 18: Communications

    COMMUNICATIONS Since the meter does not handle a great deal of data, the link has been optimized to allow the user, through very simple instructions, to control and interrogate the meter. The following section describes the JPC Protocol used by the meter. NOTE: RS232 is only available on DPM-1200 and DPM-1300 models.
  • Page 19 READ/WRITE COMMANDS The READ command is utilized to read from the System any of the gathered data. The command is entered as a letter followed by 2 numbers, followed by a carriage return: R(Location)(Return) The 'R' indicates to the Controller that the command is to be a READ command. The Location contains two digits that indicate the data location that is to be read.
