4. Instruccions de funcionament

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 Mesura

Figure 4.2: Measuring AC voltage at an electrical outlet using the multimeter.

1. Gireu el selector de funcions al volum de CA desitjattage (V~) o Volum de corrent continutage (V=) range.
2. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
3. Toqueu les sondes de prova als punts on voleu mesurar el volumtage.
4. Llegeix el voltage valor a la pantalla LCD.

4.2 Mesura de corrent continu

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. Open the circuit where you want to measure current and connect the multimeter in series.
5. Read the current value on the LCD screen.

4.3 Mesura de la Resistència

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.
3. Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
4. Touch the test probes across the component or circuit you wish to measure.
5. Read the resistance value on the LCD screen.

5. Manteniment

5.1 Substitució de la bateria

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 Neteja

Wipe the multimeter's casing amb anunciamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is completely dry before use.

5.3 Canvi de fusibles

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. Solució De Problemes

• Sense pantalla o pantalla tènue: 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.
• "OL" (Overload) displayed: The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the multimeter's capabilities.
• Lectures inexactes: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
