Measurement
Measure AC voltage across the current
input.
Measure DC voltage across the current
input.
Measure the DC current across the
current input.
Measurement
Measure AC voltage across the
resistive termination.
Measure DC voltage across the
resistive termination.
Measure the resistance across the
resistive termination.
Expected Value
Vac ≈ 0.0 V
AC voltage will affect further
measurement.
Vdc ≈ 0.0 V
Compare the measured current with
the expected value based on the
manufacturer's specification and
current conditions.
Expected Value
Vac ≈ 0.0 V
AC voltage will affect further
measurement.
Vdc ≈ 0.0 V
DC voltage will affect further
measurements.
