4. Podešavanje
4.1 Instalacija baterije
The GD166B requires 3 x 1.5V AAA batteries (not included) for operation.
- Pronađite odjeljak za baterije na stražnjoj strani mjerača.
- Koristite odvijač da otvorite poklopac pretinca za baterije.
- Insert three AAA batteries, ensuring correct polarity (+ and -).
- Vratite poklopac odeljka za baterije i pričvrstite ga vijkom.
4.2 Spajanje mjernih kabela
Za mjerenja koja zahtijevaju mjerne kablove (npr. voltage, resistance, continuity, diode, capacitance, temperature), connect them as follows:
- Umetnite crni mjerni kabel u ulazni priključak "COM" (zajednički).
- Insert the red test lead into the "INPUT" (positive) input jack.

Figure 4.2.1: Test Lead Connection. This image illustrates the correct way to connect the test leads to the meter's input jacks for various measurements.
5. Uputstvo za upotrebu
5.1 Uključivanje/isključivanje napajanja
Pritisnite Dugme za napajanje (⑂) to turn the meter on or off.
5.2 Odabir funkcije
The GD166B features a "Smart Measurement (Auto)" mode, which automatically identifies the measurement type (voltage, resistance, continuity) when test leads are connected. For other specific functions, use the FUNC button to cycle through modes or the rotary dial if present (though this model appears button-driven).
5.3 Common Measurements
5.3.1 AC/DC Voltage Measurement
- Spojite crveni mjerni kabel na "INPUT" priključak, a crni mjerni kabel na "COM" priključak.
- Odaberite odgovarajući volumentage range (or use Smart Auto mode).
- Spojite mjerne kablove paralelno sa strujnim kolom ili komponentom koju treba mjeriti.
- Pročitajte voltage vrijednost na ekranu.
5.3.2 Mjerenje AC/DC struje (Clamp)
Za mjerenja struje koristite clamp jaw. Ensure the circuit is de-energized before clamping.
- Select the AC or DC current function.
- Otvorite clamp jaw and enclose only one conductor of the circuit.
- Zatvorite clamp jaw completely.
- Očitajte trenutnu vrijednost na displeju.
5.3.3 Mjerenje otpora
- Prije mjerenja otpora provjerite je li strujno kolo bez napona.
- Connect the test leads to the "INPUT" and "COM" jacks.
- Select the resistance function.
- Spojite mjerne kablove preko komponente koju treba mjeriti.
- Očitajte vrijednost otpora na zaslonu.
5.3.4 Test kontinuiteta
- Osigurajte da je strujni krug bez napona.
- Connect the test leads to the "INPUT" and "COM" jacks.
- Select the continuity function.
- Spojite mjerne kablove preko strujnog kola ili komponente. Neprekidni zvučni signal označava kontinuitet (nizak otpor).
5.3.5 Non-Contact Voltage (NCV) Detekcija
NCV funkcija omogućava detekciju AC volumnatage bez direktnog kontakta.
- Select the NCV function.
- Place the top end of the meter near the conductor or outlet.
