4. Podešavanje

4.1 Instalacija baterije

1. Provjerite je li mjerač ISKLJUČEN.
2. Pronađite poklopac odjeljka za baterije na stražnjoj strani mjerača.
3. Koristite odvijač da otpustite vijak(e) i uklonite poklopac.
4. Umetnite novu 9V bateriju, pazeći na ispravan polaritet (+ i -).
5. Vratite poklopac odjeljka za baterije i pričvrstite ga vijkom (vijcima).

4.2 Spajanje mjernih kabela

1. Za voltage, resistance, and frequency measurements, insert the black test lead into the COM terminal.
2. Umetnite crveni test kabl u VΩHz terminal.
3. For specific 2-channel measurements or other functions requiring a second input, refer to the operating instructions for connecting to the CH2 terminal.
4. Prije nego što nastavite s mjerenjima, provjerite jesu li spojevi sigurni.

5. Uputstvo za upotrebu

5.1 Opći postupak mjerenja

1. Okrenite rotirajući brojčanik na željenu funkciju mjerenja.
2. Spojite mjerne kablove ili clamp the jaws to the circuit under test as appropriate for the selected function.
3. Read the measurement value(s) on the dual LCD display.
4. If the reading is unstable or out of range, adjust the function or range if manual ranging is available.

5.2 Mjerenje AC/DC struje (Clamp)

This function measures current without breaking the circuit.

1. Okrenite okretni točkić na A~ (AC struja) ili A- (jednosmjerna struja) položaj.
2. Otvorite clamp čeljusti pritiskom na okidač.
3. Zatvorite samo jedan provodnik strujnog kola unutar čeljusti. Osigurajte da su čeljusti potpuno zatvorene.
4. Read the current value on the display. For DC current, observe the polarity.

5.3 AC/DC Voltage Measurement

1. Spojite crni ispitni vod na COM terminal i crveni ispitni kabl do VΩHz terminal.
2. Okrenite okretni točkić na V~ (AC Voltage) ili V- (DC Voltage) položaj.
3. Touch the test probes to the desired test points in the circuit.
