Presence of direct component give false measurement.
RESISTANCES
If the "Voltest" light comes on, unplug the leads immediately.
Present voltage is upper to 15V AC or DC.
I To get the resistance in Ω, multiply the reading on the Ω scale
(green) by the coefficient of the selected range: x 1 or x 100.
The zero adjusting is automatic. To keep the battery autonomy,
avoid to untouch the rotary switch on the ranges.
