3. Podešavanje
3.1. Instalacija baterije
- Provjerite je li multimetar isključen i da su svi mjerni kabeli isključeni.
- Pronađite poklopac odjeljka za baterije na stražnjoj strani mjerača (pogledajte sliku 1).
- Odvrnite vijak(e) za pričvršćivanje i pažljivo uklonite poklopac.
- Insert a new 9V battery (NEDA 1604 or 6F22 type), observing the correct polarity (+ and -).
- Vratite poklopac odjeljka za baterije i pričvrstite ga vijkom (vijcima).
3.2. Povezivanje ispitnih vodova
- Povežite crvena test lead to the "VΩmA" input jack.
- Povežite crna test lead to the "COM" (common) input jack.
- For current measurements exceeding 200mA (up to 10A), connect the red test lead to the "10A" input jack.
4. Uputstvo za upotrebu
4.1. Odabir funkcije
Turn the rotary switch to the desired measurement function and range. Always start with a higher range if the approximate value is unknown to prevent overloading the meter.
4.2. Mjerenje DC Voltage (V–)
- Podesite rotacijski prekidač na željenu jačinu jednosmjerne struje (DC Vol).tage (V–) range (e.g., 20V, 200V).
- Spojite crveni mjerni kabel na pozitivnu (+) stranu strujnog kola, a crni mjerni kabel na negativnu (-) stranu.
- Pročitajte voltage vrijednost na LCD zaslonu.
4.3. Mjerenje AC Voltage (V∼)
- Podesite rotacijski prekidač na željenu jačinu AC strujetage (V∼) range (e.g., 200V, 750V).
- Spojite mjerne kablove preko AC voltažetage izvor.
- Pročitajte voltage vrijednost na LCD zaslonu.
4.4. Measuring DC Current (A–)
Oprez: To measure current, the meter must be connected in series with the circuit. Never connect the meter in parallel with a voltagizvor kada je u strujnom režimu, jer to može oštetiti mjerač i strujni krug.
- Set the rotary switch to the desired DC Current (A–) range (e.g., 20mA, 200mA, 10A).
- For currents up to 200mA, ensure the red lead is in the "VΩmA" jack. For currents up to 10A, move the red lead to the "10A" jack.
- Otvorite strujni krug u kojem treba mjeriti struju i spojite mjerač serijski.
- Očitajte trenutnu vrijednost na LCD zaslonu.
4.5. Mjerenje otpora (Ω)
Oprez: Prije mjerenja otpora provjerite je li strujno kolo ili komponenta koja se testira bez napona.
- Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 200kΩ).
- Spojite mjerne kablove preko komponente ili strujnog kola koje se mjeri.
- Očitajte vrijednost otpora na LCD ekranu.
4.6. Test diode (→|–)
- Set the rotary switch to the Diode Test (→|–) position.
- Spojite crveni mjerni kabel na anodu diode, a crni mjerni kabel na katodu.
- Na ekranu će se prikazati jačina zvuka naprijedtagpad napona (obično od 0.5 V do 0.8 V za silicijumske diode).
- Reverse the leads. The display should show "OL" (Open Loop) for a good diode.
4.7. Transistor (hFE) Test
- Postavite okretni prekidač u položaj hFE.
- Odredite da li je tranzistor NPN ili PNP.
- Insert the transistor's emitter, base, and collector leads into the corresponding sockets on the hFE test socket.
- Read the hFE (DC current gain) value on the display.
5. Održavanje
5.1. Zamjena baterije
Kada se na ekranu pojavi indikator slabe baterije, zamijenite 9V bateriju kao što je opisano u odjeljku 3.1. Korištenje slabe baterije može dovesti do netačnih očitanja.
5.2. Zamjena osigurača
If the current measurement function stops working, the fuse may need replacement. This operation should only be performed by qualified personnel.
- Provjerite je li multimetar isključen i da su svi mjerni kabeli isključeni.
- Open the back casing of the meter (this may involve more screws than just the battery compartment).
- Locate the blown fuse and replace it with a fuse of the exact same type and rating (e.g., F200mA/250V for mA range, F10A/250V for 10A range). Refer to the internal markings or specifications for precise fuse ratings.
- Carefully reassemble the meter, ensuring all screws are tightened.
5.3. Čišćenje
Obrišite mjerač oglasomamp cloth and mild detergent. Do not use abrasives or solvents. Keep the meter dry.
