8.3.3 Calibration Point

1. Perform calibration for each range of each measurement function. For more information on relation-

ships between functions and ranges, refer to Table 5-2.

2. First, calibrate the zero point in each range calibration.

3. In the DC voltage measurement (includes DCV-Bch) and DC current measurement, calibrate the zero

point and full-scale point.

4. In the resistance measurement, calibrate the zero point and full-scale point for 4W measurement

and calibrate only zero point for 2W measurement.

5. In the low-power resistance measurement, calibrate the zero point and full-scale point for 4W mea-

surement and calibrate only zero point for 2W measurement.

6. In the AC voltage measurement and AC current measurement, calibrate the zero, 1/100 full-scale, 1/

10 full-scale, and full-scale points.

7. In the ACV(AC+DC) and ACI(AC+DC) measurements, no calibration is required because the instru-

ment is calibrated when the calibration is performed in the DC voltage and AC voltage measurements.

8. In the continuity, diode and temperature measurement, no calibration is required because the instru-

ment is calibrated when the calibration is performed in the DC voltage and AC voltage measurements.

9. In the frequency measurement, no calibration is required.
