6.2 Mjerenje AC/DC struje

1. Postavite funkcijski točkić na A~ (AC Current) or A- (DC Current) position.
2. For currents up to 200mA, insert the red test lead into the VΩmA jack. For currents up to 10A, insert the red test lead into the 10A jack. The black test lead always goes into the COM Jack.
3. UPOZORENJE: Connect the multimeter in series with the circuit. Do not connect in parallel across a voltage source when measuring current, as this can damage the meter and circuit.
4. Očitajte trenutnu vrijednost na LCD zaslonu.

6.3 Mjerenje otpora

1. Postavite funkcijski točkić na Ω (Pozicija otpora).
2. Umetnite crveni test kabl u VΩmA jack and the black test lead into the COM Jack.
3. Prije mjerenja otpora provjerite je li strujno kolo ili komponenta bez napona.
4. Spojite ispitne sonde preko komponente.
5. Očitajte vrijednost otpora na LCD ekranu.

• No Display / Power On Issue: Check battery installation and charge. Replace battery if necessary.
• "OL" Displayed:
  • In resistance mode: Indicates an open circuit or resistance beyond the meter's range.
  • In diode mode (reverse bias): Normal for a good diode.
  • In current mode: Indicates current exceeding the selected range. Switch to a higher range (e.g., 10A jack) or check for an open circuit.
• Netačna očitavanja:
  • Provjerite nivo baterije.
  • Ensure test leads are fully inserted and not damaged.
  • Verify the correct function and range are selected.
• Nema zvučnog signala kontinuiteta: Ensure the continuity function is selected (speaker icon on display). Check if the circuit resistance is above 100Ω.
