Hanna HI 931002

HI 931002 Versatile 4-20 mA Amperometer, Simulator and Calibrator all rolled into one

HI 931002 is a portable instrument designed by the plant Repair and Maintenance Operators for the RMO! 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:
i) Passive Drive/Calibrator Mode: HI 931002 can set the 4-20 mA current values and the user can then adjust the process meter accordingly.
ii) 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.
iii) Passive Measurement/Tester Mode: HI 931002 practically becomes an Amperometer. It measures and displays the mA (or pH) values transmitted by the process meter.
iv) Active Measurement/Tester Mode: Same as iii) above in addition to providing voltage to the 4-20 mA bus. HI 931002 can practically measure incoming current, provide power and simulate 4-20 mA output to calibrate your process meter. A large LCD shows values on the display. You can select between drive and measurement modes through a switch on the front panel and two dials allow for quick adjustment of the current. Another innovative feature of HI 931002 is that the battery only serves to power the display and the calibrator continues to operate without it in the passive modes.
HI 931002 is supplied complete with 9V battery, HI 710005 or HI 710006 12VDC adapter, 1 meter (3.3') connection cables and instruction manual.
