•
Never use the meter if the meter or test leads look damaged.
•
Be sure the test leads and switch are in the correct position for
the desired measurement.

Never measure resistance in a circuit when power is applied.
•
Never touch the probes to a voltage source when the test
leads are plugged into the 10 A or 300 mA input jack.
