Potential-free high voltage precision voltmeter for DC voltage with a measuring range of max. ±20kV resolution of 1mV
and highest accuracy. Automatic range switching enables an accuracy of ±0.02% of the measured value
2kV and ±0.04% to 20kV. The relative error with respect to the measured value is only ±0.002V and ±0.01V respectively.
The measuring part is designed symmetrically isolated for 20kV, so that voltages that are high to earth at a potential of up to 20kV can be measured with high accuracy without additional probes.
The input impedance is 1GΩ.
Two high-voltage sockets and a 7½ LED display are located on the front of the device.
An RS-232 PC interface is located on the rear of the instrument, allowing access to the full range of functions of the HV precision voltmeter.
Due to these outstanding characteristics, the instrument can also be used as a reference standard in accredited calibration laboratories and factory calibration centers.
