Modes of Operation
MEASURE (Input) Mode of Operation
In this mode, the unit will measure up to 50mADC.
1. Slide the function switch to the SOURCE/MEASURE position.
2. Turn the meter ON
3. Press the MODE button to select MEASURE
4. Connect the Calibration Cable to the meter.
5. Connect the Calibration Cable to the device or circuit under test.
6. Read the measurement on the LCD display.
SOURCE (Output) Mode of Operation
In this mode, the unit can source current up to 24mADC at 1000 ohms
1. Slide the Mode switch to the SOURCE/MEASURE position
2. Turn the meter ON
3. Press the MODE button to select SOURCE
4. Use the UNIT button to select % or mA units of measure
5. Connect the Calibration Cable to the meter
6. Connect the Calibration Cable to the device or circuit under test
7. Use the
▲ ▼buttons to select the desired output value. Use the LCD display to
verify the output level. Alternatively, use the stored calibration values in memory as
described in the MEM button section.
8. Note that while the SOURCE display icon is blinking the calibrator is preparing to
provide an output but only after the icon stops blinking will the current actually be
sourced.
9. For the -25% to 125% output range the output is 0 to 24mA. Refer to the Table
below.

POWER/MEASURE Mode of Operation
In this mode the unit can measure current up to 24mA and power a 2-wire current loop.
The loop voltage is 24V.
1. Slide the function switch to the POWER/MEASURE position.
2. Turn the meter ON
3. Connect the Calibration Cable to the meter.
4. Connect the Calibration Cable to the loop. Open the current loop at any convenient
location along the signal path.
5. Read the measurement on the LCD display.
6. Use the UNIT button to select % or mA units of measure. In “%” mode the display
will read from -25.0 to +230.0% representing 0.00 to 50.00mA.
