4. Podešavanje
4.1 Instalacija baterije
The PeakTech P 3131 requires two 1.5V AAA batteries (included). To install or replace batteries:
- Uvjerite se da je uređaj ISKLJUČEN.
- Pronađite poklopac odjeljka za baterije na stražnjoj strani mjerača.
- Upotrijebite odvijač da otvorite odjeljak.
- Insert the two AAA batteries, observing correct polarity (+ and -).
- Vratite poklopac odeljka za baterije i pričvrstite ga vijkom.
When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate measurements.
4.2 Spajanje mjernih kabela
Za voltage, resistance, and continuity measurements, connect the supplied test leads:
- Umetnite crni test kabl u COM (common) input terminal.
- Umetnite crveni test kabl u VΩ ulazni terminal.

5. Uputstvo za upotrebu
5.1 Uključivanje/isključivanje napajanja
Rotate the function selector dial from the "OFF" position to any desired measurement function to power on the meter. To power off, rotate the dial back to "OFF". The meter features an automatic power-off function (can be deactivated) to conserve battery life.
5.2 Mjerenje AC/DC struje (Clamp)
Za mjerenje struje bez prekidanja strujnog kola:
- Okrenite birač funkcija na A~ (AC struja) ili A= (jednosmjerna struja) položaj.
- Pritisnite AC/DC button if you need to switch between AC and DC current modes (if the dial position combines them).
- Pritisnite NULA button to zero the display before measuring DC current, especially for small currents, to compensate for residual magnetism.
- Otvorite clamp vilicu pritiskom na okidač.
- Samo priložite jedan conductor with the clamp vilica. Provjerite je li vilica potpuno zatvorena.
- Očitajte trenutnu vrijednost na LCD zaslonu.

5.3 AC/DC Voltage Measurement
Za mjerenje voltage:
- Spojite mjerne kablove kao što je opisano u Odjeljku 4.2.
- Okrenite birač funkcija na V~ (AC Voltage) ili V= (DC Voltage) položaj.
- Spojite mjerne sonde paralelno na strujno kolo ili komponentu koju želite mjeriti.
- Pročitajte voltage vrijednost na LCD zaslonu.
5.4 Resistance and Continuity Measurement
To measure resistance or check for continuity:
- Spojite mjerne kablove kao što je opisano u Odjeljku 4.2.
- Okrenite birač funkcija na Ω/))) (Resistance/Continuity) position.
- For resistance: Connect the test probes across the component. Ensure the circuit is de-energized.
- For continuity: Touch the test probes to the two points you want to check. A continuous beep indicates a low-resistance path (continuity).
- Očitajte vrijednost otpora na LCD ekranu.
5.5 Posebne funkcije
- Pravi RMS: The meter measures True Root Mean Square values for AC voltage and current, providing accurate readings for non-sinusoidal waveforms.
- Zadržavanje podataka (H): Pritisnite H/MAX kratko pritisnite dugme da biste zamrznuli trenutno očitavanje na ekranu. Pritisnite ponovo da biste otpustili.
- Maximum Value Hold (MAX): Pritisnite i držite H/MAX button to capture and display the maximum measured value. Press again to exit.
- ZERO Function: Used to zero the display for DC current measurements to eliminate offset errors.
- Automatsko podešavanje raspona: The meter automatically selects the appropriate measurement range.
- Automatsko isključivanje: The meter automatically turns off after a period of inactivity to save battery. This feature can typically be disabled by holding a specific button during power-on (refer to the device's on-screen indicators or a more detailed manual if available).
6. Održavanje
