Fig 3-3 An Equivalent Circuit In Terms Of The Current Monitor - Prodigit 3110 Series Operation Manual

3.2.24. I-monitor
The I-monitor is provided as a BNC socket. It is designed to enable the user to
Monitor the Electronic Load's input current or short current. The I-monitor's signal
Is 0V to 10V. This signal is proportional to the full scale current that the particular
Electronic Load module is capable of.
For example. 3110: Imax = 50A therefore I-monitor 10V = 50A so 1V = 5A
Please refer to the specification Table 1-1 for the maximum current that each
3110 series module is capable of.
The current monitor of this unit is NOT isolated. Please be careful when you connect an
oscilloscope. Improper connections are likely to cause damage.
