5. Upute za rad

5.1 Uključivanje/isključivanje i odabir funkcija

To power on the multimeter, rotate the central rotary switch from the 'OFF' position to the desired measurement function. To power off, rotate the switch back to 'OFF'.

5.2 Mjerenje DC Voltage (V–)

1. Set the rotary switch to the 'V–' range. Select an appropriate range (e.g., 4V, 40V, 400V) higher than the expected voltage. Ako je objtagAko je e nepoznato, počnite s najvišim rasponom i smanjite ga po potrebi.
2. Spojite crveni mjerni kabel na pozitivni (+) pol strujnog kruga, a crni mjerni kabel na negativni (-) pol.
3. Pročitajte svtage vrijednost na zaslonu.

5.3 Mjerenje AC Voltage (V∼)

1. Set the rotary switch to the 'V∼' range. Select an appropriate range higher than the expected voltage.
2. Spojite mjerne kabele preko AC voltatage izvor.
3. Pročitajte svtage vrijednost na zaslonu.

5.4 Mjerenje istosmjerne struje (A–)

Oprez: Nikada ne spajajte multimetar paralelno s voltmetrom.tage source when measuring current. Always connect it in series with the load. Ensure the correct input jack (VΩmA or 10A) is used.

1. Isključite strujni krug.
2. Break the circuit at the point where current is to be measured.
3. Set the rotary switch to the 'A–' range (e.g., µA, mA, or 10A).
4. Connect the red test lead to the appropriate current input jack (VΩmA for up to 400mA, 10A for up to 10A).
5. Spojite multimetar serijski s krugom.
6. Restore power to the circuit and read the current value.

5.5 Measuring AC Current (A∼)

Follow the same safety precautions and connection method as for DC current, but set the rotary switch to the 'A∼' range.

5.6 Measuring Resistance (Ω)

Oprez: Ensure the circuit is de-energized before measuring resistance. Do not measure resistance on a live circuit.

1. Turn off power to the circuit or component.
2. Set the rotary switch to the 'Ω' range.
3. Spojite mjerne kabele preko komponente ili strujnog kruga koji se mjeri.
4. Očitajte vrijednost otpora na zaslonu.

5.7 Posebne funkcije

• Tipka FUNC: Used to switch between different functions within a single rotary switch position (e.g., AC/DC, Diode/Continuity).
• Tipka HOLD: Zamrzava trenutno očitanje na zaslonu. Ponovno pritisnite za otpuštanje.
• Gumb MAX: Displays the maximum measured value.
• Gumb za pozadinsko osvjetljenje: Activates or deactivates the display backlight for better visibility in low-light conditions.

6. Održavanje

6.1 Čišćenje

To maintain accuracy and prevent damage, keep the multimeter clean and dry. Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure no moisture enters the meter.

6.2 Zamjena baterije

Kada se na zaslonu pojavi indikator baterije, odmah zamijenite baterije kako biste osigurali točna očitanja. Upute za ugradnju baterija potražite u Odjeljku 4.1.

6.3 Skladištenje

If the multimeter is not used for an extended period, remove the batteries to prevent leakage and damage. Store the instrument in a cool, dry place away from direct sunlight and extreme temperatures.

7. Rješavanje problema

• Nema zaslona: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. Ensure the rotary switch is not in the 'OFF' position.
• Netočna očitanja: Verify that the test leads are properly connected to the correct input jacks and that the rotary switch is set to the appropriate function and range. Ensure the circuit is de-energized for resistance measurements.
• No Reading for Current: Check if the fuse is blown. If measuring high current, ensure the red lead is in the 10A jack.
• Display Shows 'OL' (Overload): The measured value exceeds the selected range. Switch to a higher range or ensure the input is within the meter's maximum specifications.

9. Sigurnosne informacije

• Prije upotrebe uvijek provjerite multimetar i mjerne kabele ima li oštećenja. Ne koristite ako su oštećeni.
• Nemojte primjenjivati ​​voltage or current that exceeds the maximum rated input for any range.
• Budite oprezni pri radu s voltagiznad 30 V AC RMS, 42 V peak ili 60 V DC. Ovi volumenitagpredstavljaju opasnost od strujnog udara.
• Uvijek odspojite mjerne kabele iz strujnog kruga prije promjene funkcija ili raspona.
• Ne koristite mjerač u eksplozivnim plinovima, parama ili prašnjavim okruženjima.
• Ensure your hands are dry when operating the meter.
