4_Enter-1.6V according to the prompt of zone 3 in Figure 8- L. Press Enter key after the measured
value is stable.
5. Enter-2.2V according to the prompt of zone 3 in Figure 8- 1. Press Enter key afler the measured
value is stable.
6. Enter 2V according to the prompt of zone 3 in Figure 8- 1. Press Enter key after the measured
value is stable.
7. The calibration program jump to 20V range automatically.
Atthis point, 2V range calibration is completed, the calibration data written to FLASH. You can
press any of the basic function keys to exit the calibration function, or you can choose to continue
calibrating the next range.
20V calibration steps:
1 Enter OV according to the prompt of zone 3 in Figure 8- L. Press Enter key after the measured
value in area 5 is stable.
2. Enter 20V according to the prompt of zone 3 in Figure 8- 1. Press Enter key after the measured
value is stable.
3. The calibration program jump to 200V range automatically.
At this point, 20V range calibration is completed, the calibration data written to FLASH. You can
press any of the basic function keys to exat the calibration function, or you can choose to continue
calibrating (he next range
200V calibration steps:
1 Enter OV according to the prompt of zone 3 1 Figure 8- 1 Press Enter key afler the measured
value m area 5 is stable
2. Enter 200V according to the prompt of zone 3 in Figure 8- 1. Press Enter key after the measured
value is stable.
3 'The calibration program jump to 1000V range automatically
At this point, 200V range calibration is completed, the calibration data written to FLASH. You can
press any of the basic function keys to exit the calibration function, or you can choose to continue
calibrating the next range
1O0OV calibration steps:
