1. Use 5520A 2-Wire Comp.
2. Zero ohms must use the same calibrator and test leads as all other ohm cal points.
Do not bypass the calibrator with a shorting bar for the zero ohms step.
3. Because of capacitive coupling, readings will be affected by movement of the leads or
operator. Put fingers on UP button and wait for display reading to settle before pushing.
