GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
HI 931002 is a portable 4-20 mA simulator, ammeter and calibrator
designedspecifically formonitoring andregulating a4-20 mAcurrent
loopfrompracticallyanyprocessmeterwithorwithoutvoltagesource.
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.
Dear Customer,

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 931002simulates 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.
• Disconnectthe external poweradapter fromHI 931002 ifpresent.
• 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.
• Wirethe calibrator"Com." and "P" connectors tothe DeviceUnder
Test (D.U.T.) input contacts (see page 4, #10 and #9 respec-
tively) 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.

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.
• Disconnectthe external power adapter from HI 931002if present.
• Turn the meter on by pressing the ON/OFF key.
• Selectthemeasurement unit by pressingtheUNIT 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 respec-
tively) using the cables provided, paying attention to the polarity
("Com." to - and "P" to + terminals).
• VerifythattheD.U.T. displays thesamereadingof the HI931002
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 atransmitterandcanlimitcurrentbelow100mA.
WRONG OPERATION WILL BREAK THE INTERNAL FUSE.
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).
• 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.
• Wirethe calibrator"Com." and "A" connectors tothe DeviceUnder
Test (D.U.T.) input contacts (see page 4, #10 and #8 respec-
tively) 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.

BATTERY REPLACEMENT
The instruments uses a 9 volt battery that lasts for approximately
1600 hours of continuous use.
When the battery is rundown, "V" and two
decimal points blink on the LCD to warn the
user.
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.

The HI 931002 is equipped with a protection fuse inside the instru-
ment. In the event the fuse would break contact your nearest Hanna
Service.
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.
