E) Continuity Check 0 - 5 Mohm (Direct Contact); F) Practice Note; G) Microwave Leak Test ( > 5 Mw/Cm ); Maintenance And Care - VOLTCRAFT MS-18/2 Bedienungsanleitung

e) Continuity check 0 – 5 MOhm (direct contact)
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 multit-
ester to another contact. If the LED (2) starts to light up or blink, continuity is given
and the light bulb is in working order. The multitester recognises resistances up to
50 MOhm. With this function you can test fuses, resistances, (up to 50 MOhm), heat-
ing elements, electrical components such as condensers, transistors, diodes, coils,
etc. simply and easily.

f) Practice note!

• A diode is in working order if the LED starts to light up or blink 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 to light up or blink as soon as the test tip of the emitter or the
collector gets touched while the finger taps the base at the same time.
• A PNP transistor is in working order if the LED starts to light up or blink as soon as the test tip on the base is
touched while at the same time tapping the emitter or the collector with the finger.
g) Microwave leak test ( > 5 mW/cm
Caution!
Microwave radiation is dangerous. This tester can not be compared with a high-tech device. The cost for
measuring devices like this are much larger. This is why you should see this test only as an indication for
possibly existing microwave radiation.
• Switch your microwave on
• Touch the battery compartment lid (3) with one hand and guide the test tip of the multitester slowly along the door
of the microwave. If the door seal is leaky, the LED will start blinking. If this is the case, the microwave must not
be operated anymore. Take the device to a specialist.

9. Maintenance and care

Separate the multitester from all power supplies before cleaning it or carrying out maintenance. To clean the outside,
only use a soft, dry cleaning cloth. Do not get is damp or use cleaning agents. Maintenance or repairs may only be
carried out by an expert who is familiar with the relevant regulations (VDE 100, VDE 0701) (VDE mark of conformity).
