Using the Current Monitor Output
Background
The current monitor is used to measure the
voltage drop across the shunt resistors
manually.
The current monitor outputs the full scale
current input (for the selected range) as a
voltage of 0~300mV.

Steps
1.
Set the PCS-1000 for normal operation, as
described previously in this chapter, page
25~27.
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:
Input current = monitor output / shunt Ω
= 150mV/0.1Ω
= 1.5A
