served to function correctly. All defective items must be returned
to the Dealer in their original packing.

GENERAL DESCRIPTION

HI 931002 is a portable 4-20 mA simulator, ammeter and calibrator
designed specifically for monitoring and regulating a 4-20 mA current
loop from practically any process meter with or without voltage source.
Four operational modes are provided:
1) Passive Drive/Calibrator Mode. HI 931002 can be set to simu-
late 4-20 mA current values and the user can then adjust the process
meter accordingly.
2) Active Drive/Simulator Mode. HI 931002 simulates the correct
values as above in addition to providing power to the current loop.
Power is provided through an external adapter (included) which is
connected to the simulator. This mode is ideal for calibrating chart
recorders, pressure transducers or current indicators.
3) Passive Measurement/Tester Mode. HI 931002 practically be-
comes an Ammeter. It measures and displays the mA (or pH) values
transmitted by the process meter.
4) Active Measurement/Tester Mode. Same as point 3 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 almost any process meter.
A large LCD shows current values. You can select between drive and
measurement modes through a switch on the front panel and two
dials that allow for quick adjustment of the current.
