* Discharge capacitor before measurement. Discharge a large capacitor through an

appropriate resistive load.

** Tone indicates continuity. The threshold is between 20 Ω and 200 Ω.

*** For precise resistance measurements, begin in the autoranging mode and press RANGE

twice. When the meter displays “Shrt”, short the test leads together until the meter reads

“0”. The meter will now compensate for the resistance of the test leads and the internal

protection circuitry, allowing very precise resistance measurements. Changing ranges,

functions, or going back to autoranging mode will reset the meter.
