4.2 Instalacija baterije

The multimeter requires 3 x 1.5V AAA batteries. Follow these steps to install them:

1. Provjerite je li multimetar isključen iz napajanja i da li su mjerni kablovi odvojene.
2. Pronađite odeljak za baterije na poleđini multimetra.
3. Koristite odvijač da otvorite poklopac baterije.
4. Insert the 3 AAA batteries, observing the correct polarity (+/-).
5. Vratite poklopac baterije i pričvrstite ga vijkom.

5. Uputstvo za upotrebu

The HANMATEK S1 DM20 features auto-ranging for most measurements, simplifying operation.

5.1 Uključivanje/isključivanje napajanja

• Pritisnite SEL button to power on the multimeter.
• Multimetar će se automatski isključiti nakon određenog perioda neaktivnosti kako bi se uštedio vijek trajanja baterije.
• Za ručno isključivanje, pritisnite i držite SEL dugme.

5.2 Odabir funkcije

The multimeter automatically detects the measurement type (voltage, resistance, continuity) when test leads are connected. For specific functions or to switch between AC/DC, press the SEL dugme nakratko.

5.3 Osnovna mjerenja

Priključite crveni ispitni vod na INPUT terminal i crni ispitni vod do COM terminal for most measurements.

• Voltage (AC/DC): Connect test leads in parallel to the circuit or component. The multimeter will automatically detect AC or DC voltage.
• Struja (AC/DC): Connect test leads in series with the circuit. Use the A mA terminal for current measurements. Ensure the circuit is de-energized before connecting.
• Otpor: Connect test leads across the component. Ensure the component is isolated from power.
• Kontinuitet: Connect test leads across the circuit. A buzzer will sound if continuity is detected.
• Diode: Connect test leads across the diode.
• Frekvencija: Connect test leads to the signal source.

5.4 Non-Contact Voltage (NCV) Detekcija

NCV funkcija omogućava detekciju AC volumnatage bez direktnog kontakta.

1. Pritisnite NCV / Flashlight button to activate NCV mode.
2. Place the NCV detection area (top of the multimeter) near the conductor.
3. Ako je AC voltage is detected, the NCV LED will flash, and the buzzer will sound. The LCD screen will display segments ('-' to '----') indicating signal strength.

5.5 Pozadinsko osvjetljenje i zadržavanje podataka

• Pozadinsko osvetljenje: Pritisnite Backlight / Data Hold button briefly to turn the LCD backlight on/off.
• Zadržavanje podataka: Pritisnite i držite Backlight / Data Hold dugme za zamrzavanje trenutnog očitavanja na ekranu. Pritisnite ponovo za otpuštanje.

5.6 Lampa

• Pritisnite i držite NCV / Flashlight dugme za uključivanje/isključivanje ugrađene svjetiljke.

6. Održavanje

• Čišćenje: Wipe the multimeter with a damp krpa i blagi deterdžent. Ne koristite abrazive ili otapala.
• Skladištenje: Store the multimeter in a dry, cool place away from direct sunlight. If storing for extended periods, remove the batteries to prevent leakage.
• Zamjena baterije: Replace batteries promptly when the low battery indicator appears to ensure accurate readings. Refer to Section 4.2 for instructions.

7. Otkrivanje problema

• Nema prikaza/Uključeno: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Inaccurate Readings: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected (though auto-ranging handles most). Check battery level.
• No NCV Detection: Ensure NCV mode is activated. The detection area must be close to the AC voltage izvor.
• Auto Power Off Too Soon: This is a power-saving feature. The device will power off after a period of inactivity.
