" 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. 5 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). · 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. 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. · 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). IMPORTANT NOTE: Set the selection switch to MEASURE mode only if the D. U. T. WRONG OPERATION WILL BREAK THE INTERNAL FUSE. · Calibrate the D. U. T. Calibrator operational mode is functional even without a battery or if battery is discharged. 6 7 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. · Switch the selection switch to the "Measure" mode. mA - pH RELATION 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.
