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 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.
5. In the low-power resistance measurement, calibrate the zero point and full-scale point.
6. In the AC voltage measurement and AC current measurement, calibrate the zero point, calibration
point1, calibration point2, and calibration point3.
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 and diode measurements, no calibration is required because the instrument is cali-
brated when the calibration is performed in the DC voltage and AC voltage measurements.
9. In the frequency measurement, no calibration is required.
Recommended input range: +5% to -10% for each calibration point
