4.2 Сыноо өткөргүчтөрүн туташтыруу
Insert the red test lead into the 'VΩmA' input jack and the black test lead into the 'COM' input jack for most measurements. For high current measurements (10A), insert the red lead into the '10A' jack.
5. Иштөө нускамалары
The ANENG 621A features a smart mode that automatically detects the measurement type. You can also manually select functions using the touch screen.
5.1 Акылдуу режим (AUTO)
Upon powering on, the multimeter defaults to Smart Mode (AUTO). In this mode, it automatically identifies and measures AC/DC voltage, resistance, and continuity without manual selection. Simply connect the test leads to the circuit or component to be measured.
Figure 4: ANENG 621A Multimeter with test leads connected to a power outlet, displaying AC voltage and frequency. Icons for rechargeable, resistance, AC/DC voltage, AC/DC current, diode, buzzer, capacitance, frequency, temperature, NCV induction, and Live/Zero detection are shown.
5.2 Функцияны кол менен тандоо
To select specific functions not automatically detected by Smart Mode, use the touch screen buttons:
- Тtage (AC/DC): Touch the 'V' icon. The multimeter will automatically detect AC or DC.
- Каршылык (Ω): Touch the 'Ω' icon.
- Сыйымдуулук (F): Touch the 'F' icon.
- Диод/Үзгүлтүксүздүк: Touch the diode/continuity icon. Press again to toggle between diode test and continuity buzzer.
- Frequency (Hz)/Duty Cycle (%): Touch the 'Hz' icon.
- Температура (°C/°F): Connect the temperature probe to the input jacks and select the temperature function.
- Өзгөрмө/Туруктуу ток (А/мА): Ensure test leads are correctly inserted into the '10A' or 'VΩmA' jack as appropriate. Select the current function.
5.3 Контактсыз томtage (NCV) аныктоо
Activate the NCV function by touching the 'NCV' button. Bring the top of the multimeter near a live wire or electrical outlet. The device will indicate the presence of AC voltage through an audible alarm and a visual bar graph on the display.
