Using the Current Monitor Output
Background
The current monitor is used to measure the
voltage drop across the shunt resistors

Steps
1. Set the PCS-1000 for normal operation, as
Make note of the range used and the shunt that

is used for that range.
2. Connect the current monitor output to a DVM.
3. Use OHM’s law, V=IR, to determine the
current across the shunt resistor.
For example:
If we are using the 3A current range (and thus
the 0.1Ω shunt) and the current monitor
outputs 150mV, then:
If we are using the 3A current range (and thus
the 0.1Ω shunt) and the current monitor
outputs 150mV, then:
Input current = monitor output / shunt Ω
= 150mV/0.1Ω
= 1.5A
= 1.5A
