7.3 Resistance measurements
Do not perform resistance measurements on live circuits.
Make sure all capacitors in the circuit are discharged.

Notes:
Never perform resistance measurements on a live circuit and make s

completely discharged.
For resistance measurements above 3.26ML the meter needs a few s
