Huazheng HZHG -F 1.0 Class Digital Kilovoltmeter High Voltage Divider

2025-01-03

The AC/DC digital kilovolt meter consists of two main parts: a high-voltage divider and a digital kilovolt meter. The high-voltage divider is a passive resistive-capacitive type, constructed with precision low-temperature drift resistors and high-quality capacitors. The digital kilovolt meter includes a true RMS value circuit, a peak value measuring circuit, and a digital voltmeter. The high-voltage divider is connected to the digital kilovolt meter by a coaxial measuring cable. The high voltage is reduced to a sample value by the voltage divider and is then fed to the digital voltmeter. Using the function selector, the voltmeter can display DC voltage, AC effective (RMS) voltage, AC peak value, and AC peak-to-peak value, offering high measurement accuracy and ease of use.
