RESISTANCES
If the «Voltest» light comes on, unplug the leads immediately. Present voltage
is upper to 15 V
or
.
To get the resistance in Ω, multiply the reading on the Ω scale (green) by coefficient
of the selected range: x1 or x100. The zero adjusting is automatic. To keep the
battery autonomy, avoid to untouch the rotary switch on the ranges.
