Carry out calibration of ranges in accordance with Table 1. Calibration for 2 points (Input 1 and Input 2) is required other than DC range. After Input 1, carry out calibration of Input 2 repeating steps 6) and 7). For AC voltage and AC current ranges (marked with ), calibration is carried out at 50Hz or 60Hz frequency. 1) Turn the function switch from the OFF position to the
mV position while pressing the
SELECT and RANGE keys at the same time.
The display shows the “ CAL ” symbol then the “ PASS ” symbol.
2) Press the SELECT key. (The display shows the “ - ” symbol.)
3) Press the HOLD key twice. (The display shows the “ - - - ” symbol.)
4) Press the RANGE key. (The display shows the “ mV ” symbol.)
5) Connect the instrument to the calibrator with the test leads.
6) Set the calibrator to Input 1 value as an input to the instrument.
7) Press the HOLD key.
8) Be sure to confirm that the function switch and input terminal are set to the desired range.
Carry out calibration of other ranges by repeating steps 6) and 7).
9) To quit calibration, turn the function switch back to the OFF position.
Note
The model KEW1062 needs to be calibrated at mean value detection (MEAN) mode and filter on of AC current.
