5.2 Повезивање мерних каблова

For most measurements, connect the red test lead to the "VΩmA" input jack and the black test lead to the "COM" input jack. For high current measurements (10A), connect the red lead to the "10A" input jack.

6. Упутство за употребу

The ANENG 621A features an intelligent mode (AUTO) that automatically detects the measurement type. You can also manually select functions using the touch screen buttons.

Figure 7: Functional Measurement Overview.

6.1 Smart Mode (AUTO)

When powered on, the multimeter defaults to AUTO mode. In this mode, it automatically identifies and measures AC/DC voltage, resistance, and continuity. Simply connect the test leads to the circuit, and the meter will display the appropriate reading.

6.2 Ручни избор функције

Притисните тастер СЕЛ button on the touch screen to cycle through different measurement functions if you need to select a specific mode not automatically detected by AUTO mode.

6.3 ВолtagМерење (AC/DC)

1. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
2. Изаберите АЦ или ДЦ волtage mode (or use AUTO).
3. Повежите мерне сонде паралелно са колом или компонентом коју желите да мерите.
4. Прочитајте књtagе вредност на дисплеју.

7. Одржавање

• Чишћење: Обришите бројило огласомamp krpom i blagim deterdžentom. Ne koristite abrazivna sredstva ili rastvarače.
• Одржавање батерије: Recharge the multimeter regularly to maintain battery health. If not used for extended periods, charge it every few months.
• Складиштење: Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures.
• калибрација: For professional accuracy, periodic calibration by qualified personnel is recommended.

КСНУМКС. Решавање проблема

• Нема дисплеја/Укључено: Уверите се да је батерија напуњена. Повежите кабл за пуњење типа C и покушајте поново.
• Нетачна очитавања:
  • Check if the test leads are correctly inserted into the appropriate jacks.
  • Verify that the correct measurement function is selected (or use AUTO mode).
  • Ensure the circuit is properly connected and de-energized for resistance/continuity tests.
• Meter Beeps Continuously: In continuity mode, this indicates a closed circuit. In NCV mode, it indicates the presence of AC voltage.
• Display Shows "OL": This typically means Overload, indicating the measured value exceeds the meter's range for the selected function.
