CAUTION: Always ensure test leads are correctly inserted for the desired measurement to prevent damage to the multimeter or personal injury.

4. Uputstvo za upotrebu

The ANENG SZ308 features a user-friendly rotary dial for selecting various measurement functions.

Figure 4.1: The function dial allows selection of different measurement modes.

4.1 AC/DC Voltage Measurement

Slika 4.2: Mjerenje AC voltažetage at an electrical outlet using the multimeter.

1. Turn the function dial to the desired AC Voltage (V~) ili DC Voltage (V=) raspon.
2. Spojite crni mjerni kabel na COM priključak, a crveni mjerni kabel na VΩmA priključak.
3. Dodirnite mjerne sonde tačkama na kojima želite izmjeriti volumentage.
4. Pročitajte voltage vrijednost na LCD ekranu.

4.2 Mjerenje istosmjerne struje

The ANENG SZ308 can measure DC current in various ranges.

1. Turn the function dial to the desired DC Current (A=) range (e.g., 200m, 10A).
2. For currents up to 200mA, connect the black test lead to COM and the red test lead to VΩmA.
3. For currents up to 10A, connect the black test lead to COM and the red test lead to the 10A jack.
4. Otvorite strujni krug u kojem želite mjeriti struju i spojite multimetar serijski.
5. Očitajte trenutnu vrijednost na LCD ekranu.

4.3 Mjerenje otpora

1. Turn the function dial to the Resistance (Ω) range.
2. Connect the black test lead to COM and the red test lead to VΩmA.

When the low battery indicator appears on the LCD, replace the 9V battery as described in Section 3.1. Using a low battery can lead to inaccurate readings.

5.2 Čišćenje

Obrišite c multimetraasing s oglasomamp krpu i blagi deterdžent. Ne koristite abrazivna sredstva ili rastvarače. Prije upotrebe provjerite je li uređaj potpuno suh.

5.3 Zamjena osigurača

The ANENG SZ308 is equipped with internal fuses for overload protection. If the multimeter fails to measure current, the fuse may need replacement. Refer to the internal diagram or contact customer support for guidance on fuse specifications and replacement procedures. Always replace with a fuse of the same type and rating.

6. Otkrivanje problema

• Nema prikaza ili slab prikaz: Check battery installation. Replace the 9V battery if low battery indicator is on or if the display is dim.
• No reading in current mode: Check if the test leads are connected to the correct current jacks (VΩmA or 10A) and if the fuse is intact.
• Prikazano je "OL" (preopterećenje): The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the multimeter's capabilities.
• Netačna očitanja: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
