VOLTCRAFT 12 07 47 Bedienungsanleitung Seite 20

Continuity Check 0 – 5 MOhm (direct contact)
Caution!
Lethal danger because of risk of electric shock.
The object to be tested has to be off circuit, electrical
components must be removed. Devices which are
operated with batteries, rechargeable batteries or a
power supply unit, have to be disconnected from the
voltage supply. With 230V alternating voltage devices
the mains plug needs to be pulled. With 230V lines the
main fuse needs to be switched off and must be safe-
guarded to prevent unintentional reclosing. Possibly
built-in capacities have to be discharged.
Practice note
- A diode is in working order if the LED starts blinking in conducting
direction (finger on cathode, test tip on anode), the LED remains
dark in reverse direction.
- A NPN transistor is in working order if the LED starts blinking as
soon as the test tip of the emitter or the collector gets touched
while the finger taps the base at the same time.
Touch the battery compartment lid (3) with one
hand and with the other hand the contact of the
component to be tested (e.g., light bulb). Guide
the tip of the multitester to another contact. If
the LED (2) starts to blink, continuity is given
and the light bulb is in working order. The mul-
titester recognises resistances up to 50MOhm.
With this function you can test fuses, resis-
tances, (up to 50Mohm), heating elements,
electrical components such as condensers,
transistors, diodes, coils, etc. simply and easily.
