Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipment.
If noticeable damage is found, immediately notify your Dealer.
In addition to this manual you should find the following items:
•
HI 931002
•
12 VDC power adapter (HI710005 or HI710006);
•
1 m (3.3') connection cables;
•
9 V battery.

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 simulate 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 becomes 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.

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

INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Slide off the
battery compartment cover on the back of the meter (see page 9),
install the battery while paying attention to its polarity.
PASSIVE DRIVE (CALIBRATOR) MODE
This mode is intended to calibrate an active receiver unit.
The HI 931002 simulates 4 to 20 mA current, powered by the active
receiver from the 4-20 mA bus. The current value displayed on the
LCD, can be adjusted through two single turn potentiometers in
increments of 0.01 mA.
• Disconnect the external power adapter from HI 931002 if present.
• Turn the meter on by pressing the ON/OFF key.
• Select the measurement unit by pressing the UNIT key.

6) fine setting knob
7) Ext. power adapter socket
8) "A" connector
9) "P" connector
10) "Com." connector.
• Switch the selection switch to the "Drive" mode.
• Wire the calibrator "Com." and "P" connectors to the Device Under
Test (D.U.T.) input contacts (see page 4, #10 and #9 respectively) using the cables provided, paying attention to the polarity
("Com." to - and "P" to + terminals).
• Turn the Fine and Coarse knobs to any desired value and make
sure that the D.U.T. reflects the current value displayed on the HI
931002 LCD.
• Calibrate the D.U.T. according to manufacturer instructions if necessary.
