1. Overview
B High-voltage DC digital voltmeter is a DC high-voltage measuring instrument produced using advanced integrated circuit technology and DC high-voltage dividing technology. It has high input resistance (&), fast measurement speed, strong overload capability, high accuracy, light weight and easy to carry. This instrument is an ideal instrument for measuring DC high voltage. The working voltage of the megohmmeter is DC voltage. In the past, an electrostatic voltmeter was used to measure it. However, the electrostatic voltmeter is an instrument for measuring effective values. Even if the rectifier circuit of the megohmmeter is damaged, the electrostatic voltmeter will still display the reading. High-voltage DC digital voltmeters are gradually replacing electrostatic voltmeters to measure the open circuit voltage and median voltage of megohmmeters. It will be an instrument for measuring DC voltage specified in the future megohmmeter calibration regulations.
