Checkout Procedure 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 (
∞)
contact closed = shorted (0Ω)
