Expected Value
Step 1
Measure AC voltage across the current
input.
Vac ≈ 0.0 V
AC voltage will affect further
measurement.
Step 2
Measure DC voltage across the current
input.
Vdc ≈ 0.0 V
Step 3
Measure the DC current across the
current input.
Compare the measured current with
the expected value based on the
manufacturer’s specification and
current conditions.
