HV Channel Output
The test points allow to monitor the Channel Output Voltage and Current according to the following conversion:
VMON: Voltage level (1V = 136 V ±1% readout; same polarity as channel)
IMON: Voltage level (1V = 44 µA ±3% readout; positive, 0÷5 V range)
Imon Zoom
Imon Zoom is an optional feature that allows to monitor the channel current with an increased resolution (10x) in
the 0 – 20 µA range; if the Imon Zoom is installed, by selecting Imon Range = LOW (see p.16), the output current is
monitored with 0.5nA resolution (instead of 5 nA), in the 0 – 20 µA range. It is important to notice that, if Imon
Range = LOW is selected, and the channel draws a current larger than 20 µA, then Overcurrent is signalled.
