5.2 Nsopọ Awọn itọsọna Igbeyewo

Connect the test leads to the appropriate input terminals on the tester. For insulation resistance measurements, typically the red lead connects to the 'LINE' or 'VΩ' terminal and the black lead to the 'EARTH' or 'COM' terminal. Refer to the markings on the device for specific connections for different functions.

6. Awọn ilana Iṣiṣẹ

Before any measurement, ensure the circuit under test is de-energized and safely isolated, unless performing AC voltage awọn iwọn.

6.1 Idabobo Idiwon Resistance

1. Turn the rotary switch to the desired insulation resistance test voltage (fún àpẹẹrẹ, 100V, 250V, 500V, 1000V).
2. Connect the test leads to the circuit or component to be tested. Ensure proper contact.
3. Press and hold the 'TEST' button. The red warning light will illuminate, indicating high voltage jade.
4. Read the insulation resistance value on the LCD display.
5. Release the 'TEST' button to stop the measurement. The circuit will automatically discharge.

6.2 AC Voltage Idiwon

1. Turn the rotary switch to the 'ACV' position.
2. Connect the test leads to the points where AC voltage ni ki won won.
3. Awọn AC voltage value will be displayed on the LCD.

6.3 Ìwọ̀n Ìdènà Kéré Jù

1. Turn the rotary switch to the 'Ω' (Ohms) position.
2. Connect the test leads to the component or circuit for low resistance measurement.
3. Ka iye resistance lori LCD naa.

6.4 Polarization Index (PI) and Dielectric Absorption Ratio (DAR)

The UT501A can calculate PI and DAR, which are important indicators of insulation quality. These measurements typically involve taking insulation resistance readings at specific time intervals (e.g., 1 minute and 10 minutes for PI, 30 seconds and 60 seconds for DAR) and the meter automatically calculates the ratio. Refer to the detailed instructions in the full manual for specific steps on activating and interpreting these functions.
