Operation

Battery and AC Adapter Power

1. This meter can either be powered by one 9V battery or an AC adapter.

2. Note that if the meter is going to be powered by the AC adapter, remove the 9V battery from the

battery compartment.

3. If the LOW BAT display message appears on the LCD display, replace the battery as soon as

possible. Low battery power may cause inaccurate readings and erratic meter operation.

4. Use the ON-OFF switch to turn the unit ON or OFF. The meter can be automatically shut off by

closing the case with the meter on.

MEASURE (Input) Mode of Operation

In this mode, the unit will measure up to 50mADC (both models) or 20VDC (412355 only).

1. Slide the Mode switch to the MEASURE position.

2. Connect the Calibration Cable to the meter.

3. Set the Range switch to the desired measurement range.

4. Connect the Calibration Cable to the device or circuit under test.

5. Turn the meter on.

6. Read the measurement on the LCD display.

SOURCE (Output) Mode of Operation

In this mode, the unit can source current up to 24mADC (412300) or 25mADC (412355). The Model

412355 can source up to 10VDC.

1. Slide the Mode switch to the SOURCE position.

2. Connect the Calibration Cable to the meter.

3. Set the Range switch to the desired output range. For the -25% to 125% output range (Model

412300 only) the output range is 0 to 24mA. Refer to the Table below.

Display -25% 0% 25% 50% 75% 100% 125%

mA output 0mA 4mA 8mA 12mA 16mA 20mA 24mA

4. Connect the Calibration Cable to the device or circuit under test.

5. Turn the meter on.

6. Adjust the fine output knob to the desired output level. Use the LCD display to verify the output

level.

Model 412300/355-EN V1.9 9/13

POWER/MEASURE Mode of Operation (412300 only)

In this mode the unit can measure current up to 24mA and power a 2-wire current loop. The maximum

loop voltage is 12V.

1. Slide the Mode switch to the POWER/MEASURE position.

2. Connect the Calibration Cable to the meter and to the device to be measured.

3. Select the desired measurement range with the range switch.

4. Turn the calibrator on.

5. Read the measurement on the LCD.

Important Note: Do NOT short the Calibration Cable leads while in the POWER/MEASURE mode.

This will cause excess current drain and may damage the calibrator. If the cable is shorted the

display will read 50mA.

Battery Replacement

When the LOW BAT message appears on the LCD, replace the 9V battery as soon as possible.

1. Open the calibrator’s lid as far as possible.

2. Open the battery compartment (shown in Meter Description section earlier in this manual) using

a coin at the arrow indicator.

3. Replace the battery and close the cover.
