4. Упутство за употребу

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 АЦ/ДЦ Волtagе Мерење

Слика 4.2: Мерење AC јачине струјеtage at an electrical outlet using the multimeter.

1. Turn the function dial to the desired AC Voltagе (V~) или једносмерна волtage (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. Прочитајте књtagе вредност на ЛЦД екрану.

4.2 Мерење једносмерне струје

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. Очитајте тренутну вредност на ЛЦД екрану.

Обришите ц мултиметраasinг са огласомamp крпу и благи детерџент. Не користите абразивна средства или раствараче. Уверите се да је уређај потпуно сув пре употребе.

5.3 Замена осигурача

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.

КСНУМКС. Решавање проблема

• Нема дисплеја или бледи дисплеј: 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.
• Нетачна очитавања: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
