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.
• 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 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.
