2. Sigurnosne informacije
Always prioritize safety when working with electrical systems. Read and understand all instructions before using this device. Failure to follow safety guidelines may result in electric shock, fire, or personal injury.
- Ne koristite tester ako izgleda oštećeno ili ne radi ispravno.
- Ensure batteries are correctly installed before use.
- Always assume circuits are live until tested and confirmed safe.
- Wear appropriate personal protective equipment (PPE) when performing electrical work.
- This device is designed for voltage detection; it is not a substitute for proper lockout/tagvan procedure.
3. Podešavanje
3.1. Instalacija baterije
- Pronađite poklopac odjeljka za bateriju na stražnjoj strani uređaja.
- Pomaknite ili otkačite poklopac da biste otvorili pretinac.
- Umetnite dvije AAA baterije, pazeći na ispravan polaritet (+/-).
- Vratite sigurno poklopac odeljka za baterije.
3.2. Uključivanje/isključivanje
- To power on: Press and hold the power button (usually marked with a power symbol) until the device activates.
- To power off: Press and hold the power button again. The device also features an automatic shutdown after 5 minutes of inactivity to conserve energy.
4. Uputstvo za upotrebu
4.1. Podešavanje osjetljivosti
The T03B offers two sensitivity modes for varied testing environments:
- High Sensitivity (12V-1000V): Pogodno za detekciju nižih volumenatages or when a broader detection range is needed.
- Low Sensitivity (48V-1000V): Ideal for higher voltage detection or to minimize false positives in noisy electrical environments.
To switch sensitivity: Press the 'H/L' button on the device to toggle between high and low sensitivity modes.

4.2. Non-Contact Voltage (NCV) Detekcija
The NCV function allows for safe voltagdetekcija bez direktnog kontakta sa provodnicima.
- Uvjerite se da je uređaj uključen.
- Bring the tip of the tester close to the wire, outlet, or electrical component you wish to test.
- The device will emit an audible alarm and flash its red indicator light if voltage is detected. The voice broadcast feature will announce the presence of voltage.

4.3. Live/Hot Wire and Neutral Line Identification
The T03B can differentiate between live/hot wires and neutral lines:
- Live/Hot Wire: When detecting a high voltage electric field or live wire, the tester issues a "High voltage electric field, live wire" alert and flashes red.
- Neutralna linija: When detecting a low voltage or neutral field, it promptly alerts with a "caution, low voltage field" voice warning and yellow blinking lights.

4.4. Wire Breakpoint Finder
This feature helps locate breaks in insulated wires:
- Move the tester along the length of the insulated wire.
- Uređaj će prikazivati jačinu zvukatage up to the point of the break. The absence of a signal beyond a certain point indicates a break in the wire.

4.5. LED svjetiljka
The integrated LED flashlight assists in working in dimly lit areas.
- To activate the flashlight: Press the flashlight button (usually marked with a light bulb symbol).
- To deactivate: Press the flashlight button again.

5. Održavanje
5.1. Čišćenje
Obrišite uređaj suhom, čistom krpom. Ne koristite abrazivna sredstva za čišćenje ili rastvarače.
5.2. Skladištenje
Store the tester in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
6. Otkrivanje problema
- Uređaj se ne uključuje: Provjerite jesu li baterije ispravno postavljene i uvjerite se da nisu ispražnjene. Zamijenite ih ako je potrebno.
- Nedosljedna očitanja: Ensure the sensitivity mode is appropriate for the testing environment. Avoid strong electromagnetic interference.
- Nema glasovnog emitiranja: Check if the voice feature is enabled (if applicable) or if the speaker is obstructed.
