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.

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.

Battery Type/Life 9V alkaline/1600 hours of continuous use
Ext. Power Supply 12 to 32 VDC
Environment 0 to 50°C (32 to 122°F); 95% RH
Dimensions 180 x 83 x 40 mm (7.1 x 3.3 x 1.6")

• 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.
54
ACTIVE DRIVE (SIMULATOR) MODE
This mode is intended to drive a chart recorder, calibrate a pressure/
current transducer or a current indicator. The HI 931002 supplies a
voltage to the 4-20 mA bus via an external connected 12-32 VDC
power supply. The calibrator regulates the current, displayed on the
LCD, as in the previous mode (Passive Drive).
PASSIVE MEASURING (TESTER) MODE
This mode is intended to test an active transmitter. The HI 931002
reads the current produced by the transmitter via the 4-20 mA bus
and displays the reading in mA or pH units.
• 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.
• Switch the selection switch to the "Drive" mode.
• Connect the external power adapter to the power
socket on the right side of the HI 931002.
• Wire the calibrator "Com." and "A" connectors to the Device Under
Test (D.U.T.) input contacts (see page 4, #10 and #8 respectively) using the cables provided, paying attention to the polarity
("Com." to - and "A" 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.
Note: the battery powers on the display only. Calibrator operational
mode is functional even without a battery or if battery is
discharged.
• Turn the meter on by pressing the ON/OFF key.
• Select the measurement unit by pressing the UNIT key.
• Switch the selection switch to the "Measure"
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).
• Verify that the D.U.T. displays the same reading of the HI 931002
and calibrate the D.U.T. according to manufacturer instructions if
necessary.
IMPORTANT NOTE:
Set the selection switch to MEASURE mode only if the
D.U.T. is a transmitter and can limit current below 100mA.
WRONG OPERATION WILL BREAK THE INTERNAL FUSE.
76
ACTIVE MEASURING (TESTER) MODE
This mode is intended to test a passive transmitter. The HI 931002
supplies only the power to the 4-20 mA bus via an external connected
12-32 VDC power supply and displays the value of the current
produced by the transmitter.
• Turn the meter on by pressing the ON/OFF key.
• Select the measurement unit by pressing the UNIT
key.
• Switch the selection switch to the "Measure" mode.
• Connect the external power adapter to the power socket on the
right side of the HI931002.
• Wire the calibrator "Com." and "A" connectors to the Device Under
Test (D.U.T.) input contacts (see page 4, #10 and #8 respectively) using the cables provided, paying attention to the polarity
("Com." to - and "A" to + terminals).
• Verify that the D.U.T. displays the same reading of the HI 931002
and calibrate the D.U.T. according to manufacturer instructions if
necessary.
IMPORTANT NOTE:
Set the selection switch to MEASURE mode only if the
D.U.T. is a transmitter and can limit current below 100mA.
WRONG OPERATION WILL BREAK THE INTERNAL FUSE.

The HI 931002 LCD will show the current from the transmitter in mA
or in pH units according to the relation:
4 mA = 0 pH
12 mA = 7 pH mA = 1.14 x (pH reading) + 4
20 mA = 14 pH.
Press UNIT key to select the desired range. The read-
ing will toggle between the mA and pH reading.

Battery replacement must only take place in a non
hazardous area using the battery types specified in
this instruction manual (see page 4).
To change battery, slide the bottom back cover,
replace the old battery and replace the cover.
