Calibration Procedure

Before you do the verification:
1. Make sure that you have the required equipment. See Table 3.
2. Make sure the Product battery is good or replace it if necessary.
3. Warm up the Calibrator as necessary. Refer to its specifications.
4. Let the temperature of the unit under test (UUT) become stable to room temperature.
To do the verification:
1. Power on 1630-2 FC.
2. Open the clamp and make sure the surfaces fit together properly and are free of dust, dirt, or any foreign
substances. Then close the clamp. Do not attach the Clamp to a conductor or open the clamp during self-
calibration.
3. Push and hold N >2 s to turn on the Clamp. The meter will enter self-calibration mode when power on.
Self-calibration mode ends in 5 seconds. After self-calibration, the meter enters measurement mode.
To enter calibration mode:
1. In measurement mode, push and hold E.
2. Push and hold S and A until the CAL screen shows on the display.
3. To continue in calibration mode, push E to confirm.
The first calibration step shows in the display.
