5.2 Low Battery Alarm
The meter is equipped with an alarm function. If the battery capacity drops below 20%, the display will emit an audible sound and flash, alerting the user to recharge the battery.
6. Maintenance
- Cleaning: Wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: If storing the device for an extended period, ensure it is disconnected from the battery and stored in a dry, cool place.
- Inspection: Periodically check the wiring for any signs of wear or damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power, incorrect wiring, or display is off. | Check battery connections and polarity. Ensure the battery has sufficient charge. Press the Function Key to turn on the display. |
| Incorrect capacity/voltage reading | Incorrect battery type setting. | Reconfigure the battery type and voltage range using the Setting Key as per Section 4.2. |
| Alarm sounds frequently | Battery capacity is consistently below 20%. | Recharge the battery. If the issue persists after charging, the battery may be faulty or nearing end-of-life. |
| Buttons unresponsive | Device malfunction or temporary glitch. | Disconnect and reconnect power to reset the device. If the problem persists, contact customer support. |
