Taidong analysis of the use of digital high-voltage meter

Taidong company's high-voltage meter, divider is a new generation of products. Mainly used for power system and electrical and electronic equipment manufacturing department to measure industrial frequency AC high voltage and DC high voltage. The digital high voltage meter is used as follows:

1. Ground the high voltage meter ground.

2. Connect the high voltage wire above the pressure equalizing ball and tighten the high voltage wire with a wire screw.

3. Insert the input of the meter base into the measuring terminal of the digital high-voltage meter. When measuring DC, switch the toggle switch to “DC”. When measuring AC, switch the toggle switch to “AC”.

4. Select "LOW" when the measured voltage is less than 20kV, and select "HIGH" when it exceeds 20kV to obtain a more accurate test value.

5. Turn on the “Power” switch and select the appropriate gear. At this time, “000.0” or “00.00” will be displayed on the digital high voltage meter, and measurement can be started at this time.

6. After the test is completed, the high voltage is cut off, and the AC/DC digital high-voltage meter reads “000.0” or “00.00” before entering the site. When the AC test is performed, the meter will slowly return to zero, but the high voltage power supply has no electricity, so it is In this case please pay attention to the difference between AC and DC test).

7. When measuring DC, if there is a filter capacitor, it should be fully discharged to the filter capacitor, so that the reading indicated by the digital high-voltage meter is “000.0” before relevant operations can be performed.

8. In the use and maintenance, should pay attention to the digital high-pressure meter surface cleaning, to prevent contamination, this instrument should be placed in a dry place, safekeeping.
