The AC and DC voltage divider is an instrument used for field measurement, which can measure both DC high voltage and AC high voltage. The whole equipment consists of a voltage divider and a measuring instrument. The voltage divider adopts a balanced equipotential shielding structure. Electronic components are used inside the completely sealed insulating cylinder, so that the entire device has accurate testing, good linearity and stable performance.

Analysis of some common faults of AC and DC voltage divider:

1 Failure phenomenon: no response after booting, no display on the LCD screen

Troubleshooting: Replace the battery in the low-voltage display meter

2 Failure phenomenon: the test result deviation is too large

Troubleshooting: Check whether the coaxial cable is well connected

3 Failure phenomenon: There is a more obvious discharge sound during measurement

Troubleshooting: Check whether the grounding is good; the high-voltage divider may be damp, wipe the shell of the high-voltage divider with a dry cloth, and then blow it down with a dry blower for five minutes.
