Mchoro 4.2: Kupima ujazo wa ACtage at an electrical outlet using the multimeter.

1. Turn the function dial to the desired AC Voltage (V~) or DC Voltage (V=) range.
2. Unganisha risasi nyeusi ya majaribio kwenye jeki ya COM na risasi nyekundu ya majaribio kwenye jeki ya VΩmA.
3. Touch the test probes to the points where you want to measure voltage.
4. Soma juzuu yatage thamani kwenye skrini ya LCD.

4.2 Kipimo cha Sasa cha DC

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. Fungua saketi ambapo unataka kupima mkondo na uunganishe multimeter mfululizo.

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. Utatuzi wa shida

• Hakuna onyesho au onyesho hafifu: 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.
• Usomaji usio sahihi: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
