HI931002 is a portable simulator designed to monitor and regulate 4-20 mA from practically any process meter with or without a voltage generator. HI931002 can measure incoming current, provide power, and simulate 4-20 mA output to calibrate your process meter.


  • The communication bus from process instrumentation can be simulated in any of 4 modes.
  • Select between drive and measurement modes through a switch on the front panel and two dials allow for quick adjustment of the current.
  • A large LCD shows values on the display.

Passive drive/Calibrator mode

  • HI931002 can set the 4-20 mA current values and the user can then adjust the process meter accordingly.

Passive measurement/Tester mode

  • HI931002 practically becomes an Amperometer. It measures and displays the mA (or pH) values transmitted by the process meter.

Active drive/Simulator mode

  • HI931002 simulates the correct current values as above in addition to providing power to the bus communication. Power is provided through an external adapter (included) which is connected to the simulator. This mode is ideal to calibrate chart recorders, pressure transducer or current indicators.

Active measurement/Tester mode

  • HI931002 practically becomes an Amperometer. It measures and displays the mA (or pH) values transmitted by the process meter in addition to providing voltage to the 4-20 mA bus.
