RESISTANCES
If the «Voltest» light comes on, unplug the leads immediately. Present voltage
is upper to 15 V
„ 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.

CONTINUITY SOUND TEST
„ Connection and specifications: idem Resistances
„ Place the selector switch on the
„ Continuous audible beep emitted for a resistance R < 80 Ω
BATTERY CHECKING
„ Put the rotary switch on the function
„ Short-circuit the leads, the needle must be positioned on the 0 (green square) of
Ω green scale. In the contrary, change the battery.
Additional uncertainty at the § 2 and § 3 uncertainty given.
