Measurement
Expected Value
Step 1
Measure AC voltage across the resistive termination.
VAC
≈
0.0 V
AC voltage will affect further measurement.
Step 2
Measure DC voltage across the resistive termination.
VDC
≈
0.0 V
DC voltage will affect further measurements.
Step 3
Measure the resistance across the resistive termination.
contact open = infinity (
