3.2.7 I-Monitor
The I-Monitor BNC monitors the Electronic load's input current or short current. An isolated amplifier
output 0V to 10V full-scale signal indicates the zero to full-scale current for each Electronic load module.
The isolated voltage is 250V between load module and I-Monitor BNC output, and it has the same
ground potential with mainframe (i.e., GPIB ground potential).
The isolated I-Monitor feature eliminates the grounding problem while connecting I-Monitor BNC and
measuring power supply output voltage to oscilloscope simultaneously, because dual oscilloscope
channels are not isolated.
This feature is also useful in testing multiple output power supplies that have simultaneous positive and
negative polarity output, because the I-Monitor output is isolated from each load module or each power
supply output. It eliminates grounding problems while monitoring the current signal from the I-Monitor
BNC connector.
