4. Bedryfsinstruksies

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 Meting

Figuur 4.2: Meting van WS-volumetage at an electrical outlet using the multimeter.

1. Turn the function dial to the desired AC Voltage (V~) of GS Voltage (V=) range.
2. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
3. Touch the test probes to the points where you want to measure voltage.
4. Lees die voltage waarde op die LCD-skerm.

4.2 DC Current Measurement

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 Weerstandmeting

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. Maak seker dat die stroombaan gedeaktiveer is voordat weerstand gemeet word.

5. Onderhoud

5.1 Batteryvervanging

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 Skoonmaak

Vee die multimeter se c afasing met advertensieamp lap en sagte skoonmaakmiddel. Moenie skuurmiddels of oplosmiddels gebruik nie. Maak seker dat die toestel heeltemal droog is voor gebruik.

5.3 Sekeringvervanging

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. Probleemoplossing

• Geen vertoon of dowwe vertoon: 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" (Oorlading) word vertoon: The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the multimeter's capabilities.
• Onakkurate lesings: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
