Step 1
Measure AC voltage across the
voltage termination
VAC ≈ 0.0 V
AC voltage will affect further
measurement
Step 2
Measure DC voltage across the

Procedure Measurement
Expected Value
Method 1 capitalizes on the very
low input resistance of a DMM in
current measurement mode.
However, this method affects the
value that the expansion module
will use while controlling outputs.
When the meter is set to current
mode, the current flowing into the
expansion module circuit will drop
to zero or near zero.
Step 1
Measure AC voltage across the
current input
VAC ≈ 0.0 V
AC voltage will affect further
measurement
Step 2
Measure DC current across the
current input
Compare to input status in Tracer TU
