- Tutup penutup petak bateri dengan selamat.
- To check battery status, turn on the device. A dim or off white LED indicates low batteries, requiring replacement.
6. Arahan Operasi
Follow these steps to use your HIOKI Voltage Detector 3481:
- Hidupkan kuasa: Press the power button to turn on the device. The integrated tip light will illuminate.
- Laraskan Kepekaan: If your model features a sensitivity adjustment, use the dial or button to set the desired detection range. The factory default sensitivity at shipment is 80V AC.
- Kesan Voltage: Bring the tip of the detector close to the wire, outlet, or electrical component you wish to test. If AC voltage is present within the detection range, the red LED will light up, and the buzzer will sound.
- Utilize Tip Light: The integrated tip light can be used independently to illuminate dark work areas or automatically during voltagpengesanan e.
- Auto Matikan: The device will automatically power off after approximately 3 minutes of inactivity to conserve battery life.

7. Penyelenggaraan
Proper maintenance ensures the longevity and accuracy of your device:
- Pembersihan: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
- Penggantian Bateri: Replace batteries promptly when the white LED is dim or off. Always use new LR44 button alkaline batteries. Dispose of old batteries according to local regulations.
- Storan: Store the device in a cool, dry place, away from direct sunlight, high humidity, and extreme temperatures. Remove batteries if storing for extended periods (more than one month) to prevent leakage.
8. Penyelesaian masalah
If you encounter issues with your HIOKI Voltage Detector 3481, refer to the following common problems and solutions:
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| No indication (LED/Buzzer) on a known live wire. | Low batteries, device not powered on, incorrect sensitivity setting, voltage outside range. | Check battery level and replace if low. Ensure the device is powered on. Adjust sensitivity setting. Verify the wire is within the operating voltagjulat e (40V hingga 500V AC). |
| False positives (indication on a de-energized wire). | High sensitivity setting, environmental interference (e.g., static electricity, induced voltagdan). | Adjust sensitivity to a lower setting. Ensure proper grounding of the circuit being tested. Test in a different location if possible. |
| Tip light is dim or off. | Bateri lemah. | Replace all three LR44 batteries. |
| Device automatically turns off too quickly. | Normal operation (auto power-off feature). | The device is designed to power off after approximately 3 minutes of inactivity to save battery life. Turn it back on if needed. |
