Using the IPM-400 to Source and Read
Calibrate Pressure Transmitters
Display: P-XMTR, mA, mA%, DP%
Pressure Display: PSI, pa, Kpa, Mpa, Bar, mBar, Atm, Kgf/cm2, torr, mmHg, inHg, inH2O,
mmH2O, cmH2O
This function simultaneously supplies power to a two-wire pressure transmitter while
supplying the input signal to the transmitter and displaying the 4 mA to 20 mA output of the
transmitter. The meter supplies a nominal 24 VDC at 24 mA to the two-wire transmitter. The
current output of the transmitter is displayed on the meter.
• Relieve all system pressure prior to making any connections or disconnections.
• All pressure connections and test procedures must be performed by a qualified
service person, according to standard engineering practices.
Failure to observe these warnings can result in severe injury or death or equipment
damage.
Over pressurizing the pressure or vacuum module can damage the sensor.
1. Turn the Selector knob to PRESSURE. To select the desired engineering units, see the
procedure in the Read Pressure section.
2. Select the proper pressure module for the pressure range of the process and place it in
the pressure module adapter.
3. Plug the pressure module adapter cable into the pressure module adapter jack on the side
of the meter. The meter displays "– – – – – –" for up to 20 seconds while the module
powers up and is verified. The meter displays the range of the module for 3 seconds.
4. Press the °C/°F/ZERO button to zero the pressure reading.
5. Press the DISPLAY/SOURCE/READ button until "READ" and "READ" or "READ" and
"P-XMTR" appear.
6. Repeatedly press the mA/%/%DP FLOW button until the desired function appears.
