Measurement voltage
Voltage adjustable from 10V to 500VDC by 1 volt step.
Accuracy : ±(1% + 1V).
Positive pole of the HV generator is grounded ( earth)
Dynamic stability for a mains V = ±10% : >1%.
The maximum current in the measurement circuit is : 2 mA ±20%.
The discharge current is limited by a 2.2 k resistor.
Measurement range
Display : 2000 digits
The measurement range is defined by the following formula :
(Utest / Umax generator ) x 200 G*
* or 2T according to the option
This gives the following board for the 50,100, 250, 500VDC standard voltages
