Hanna's extended description

Simulator and calibrator

This portable simulator can monitor and regulate 4-20 mA from practically any process meter with or without a voltage generator. The communication bus from process instrumentation can be simulated in any of the following modes:

Passive drive/calibrator mode – HI-931002 can set the 4-20mA current values and the user can then adjust the process meter accordingly.

Active drive/Simulator mode – Hi-931002 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.

Passive measurement/tester mode – HI-931002 practically becomes an Amperometer. It measures and displays the mA (or pH) values transmitted by the process meter.

Active measurement/Tester mode– Same as above in addition to providing voltage to the 4-20mA bus.
