1000V megohmmeter function (option XS26 or MXS1000)
Measurement voltage
Voltage adjustable from
20V
to
1000VDC
by 1 volt step.
Accuracy :
±(1% + 1V).
Positive pole of the HV generator is grounded (earth)
Dynamic stability for a mains
ΔV =
±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
