XS series operating manual
XS user manual v0.55 - 24 -
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 according to the option
This gives the following board for the 100, 250, 500, 1000VDC standard voltages
Measurement accuracy
2000 digits numeric display with unity indication (K, M, G,T).
Accuracy (% of the reading, 1U = 1 digit ) :
2 T option and U<=200VDC
2 T option and U > 200VDC
CAPACITANCE mode : from 1.00M to 200G (or 2 T for option 20) with an accuracy equal to the
NORMAL mode accuracy ±100k
Input impedance = 10 M ±1%
