pHault Finder - Electrode Simulator
4-20mA Amperometer - HI931002
1. Passive Drive/Calibrator Mode:
HI931002 can set the 4-20 mA current values and the user can then adjust the process
meter accordingly.
2. 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.
3. Passive Measurement/Tester Mode:
HI931002 practically becomes an Amperometer. It measures and displays the mA (or
pH) values transmitted by the process meter.
4. Active Measurement/Tester Mode:
Same as 3 above in addition to providing voltage to the 4-20 mA bus
