5.2 Cysylltu Gwifrau Prawf

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. Cyfarwyddiadau Gweithredu

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 Manual Function Selection

Gwasgwch y SEL 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 CyftagMesuriad e (AC/DC)

1. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
2. Dewiswch AC neu DC cyftage mode (or use AUTO).
3. Cysylltwch y chwiliedyddion prawf yn gyfochrog â'r gylched neu'r gydran rydych chi am ei mesur.
4. Darllenwch y cyftage gwerth ar yr arddangosfa.

6.4 Mesur Gwrthiant

1. Ensure the circuit is de-energized and capacitors are discharged.
2. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
3. Select resistance mode (or use AUTO).
4. Cysylltwch y stilwyr prawf ar draws y gydran.
5. Darllenwch y gwerth gwrthiant ar yr arddangosfa.

7. cynnal

• Glanhau: Sychwch y mesurydd gydag hysbysebamp brethyn a glanedydd ysgafn. Peidiwch â defnyddio sgraffinyddion neu doddyddion.
• Gofal Batri: Recharge the multimeter regularly to maintain battery health. If not used for extended periods, charge it every few months.
• Storio: Storiwch y multimedr mewn lle oer, sych, i ffwrdd o olau haul uniongyrchol a thymheredd eithafol.
• graddnodi: For professional accuracy, periodic calibration by qualified personnel is recommended.

8. Datrys Problemau

• Dim Arddangosfa/Pŵer Ymlaen: Gwnewch yn siŵr bod y batri wedi'i wefru. Cysylltwch y cebl gwefru Math-C a rhoi cynnig arall arni.
• Darlleniadau anghywir:
  • 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.
