CALIBRATION PROCEDURE
Recalibrate your meter:
It is recommended that the meter may be calibrated once year. Use the following procedure to calibrate the
clamp meter.
1. Perform calibration at an ambient temperature and relative humidity (23°C±2°C and R.H.≤80%). Allow
instrument to sit at this temperature for at least thirty minutes.
2. Disconnect the test leads from any circuit under test and turn off meter.
3. Loosen the screws from the battery cover, remove battery cover and pull the battery out of battery box
with battery still connected.
4. Loosen the two screws from the bottom case.
5. Lift the bottom case.
(A) DCV Calibration (Adjust VR15)
1. Press Hold button of the meter to power on.
2. Set the output of calibrator for DCV 100V and connect to V and COM test probes.
3. Using a small flat-tip screwdriver adjust the potentiometer VR15 until display reads 100.1V
~
100.2V.
4. Disconnect the output terminals of DCV calibrator.
(B) Resistance Calibration (Adjust VR13 & VR14)
1. Set the output of calibrator for resistance 1KΩ and connect to V and COM test probes.
2. Using a small flat-tip screwdriver adjust the potentiometer VR13 until display reads 1005Ω
~
1006Ω.
3. Set the output of calibrator for resistance 100Ω and connect to V and COM test probes.
4. Using a small flat-tip screwdriver adjust the potentiometer VR14 until buzzer sounds and check 400Ω
buzzer don’t sounds.
5. Disconnect the output terminals of resistance calibrator.
(C) ACV Calibration (Adjust VR16& VR1)
1. Set the output of ACV calibrator for ACV 70V 60Hz and connect to V and COM test probes.
2. Using a small flat-tip screwdriver adjusts the potentiometer VR16 until display reads 70.0V±1d.
3. Set the output of ACV calibrator for ACV 200V 60Hz and connect to V and COM test probes.
4. Using a small flat-tip screwdriver adjusts the potentiometer VR1 until display reads 199.8V±1d.
5. Disconnect the ACV calibrator from the meter.
(D) ACA Calibration (Adjust VR17 & VR12)
1. Flow the current of ACA 100.0A 60Hz around the suitable wire or conductor.
2. Using a small flat-tip screwdriver adjusts the potentiometer VR17 until display reads 99.8A.
3. Flow the current of ACA 300.0A 60Hz around the suitable wire or conductor.
4. Position the clamp around the wire or conductor, release clamp trigger to make sure that the clamp is
entirely closed.
5. Using a small flat-tip screwdriver adjusts the potentiometer VR12 until display reads 300.0A.
6. Remove the meter away from the wire or conductor.
