Functional Features

The DC high-voltage standard source is equipped with a broadband voltage divider for voltage measurement and control, ensuring the stability and accuracy of high-voltage output.
◉ Mobile measurement and control platform: It can observe or control the output of measurement values through its LCD touch screen, and can be manually checked.
◉ Specialized verification software: Full automatic or full automatic calibration of the verified table, data recording, analysis, management, and certificate export.
The DC high-voltage standard source, secondary signal measurement of sensors, and auxiliary power supply are all isolated from each other, ensuring high system reliability.
◉ Use an optional adjustable range of 0-1M Ω DC resistance box as the load of the sensor to detect its ability to work with a load.
This device is a customized product, and the U1 output, I2 and U2 measurement ranges, sensor meter positions (number of secondary measurement channels, number of auxiliary power supplies) need to be customized according to the user's requirements.
