- Battery Care: Recharge the battery regularly, even if not frequently used, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Test Leads: Inspect test leads for any signs of damage (cracks, frayed wires) before each use. Replace damaged leads immediately to ensure safety and accurate readings.
6. Troubleshooting
If you encounter issues with your multimeter, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Multimeter does not power on. | Low or depleted battery. | Charge the multimeter using the USB Type-C cable. |
| Inaccurate readings. | Damaged test leads; Incorrect measurement mode; Environmental interference. | Inspect and replace test leads if damaged. Ensure correct mode is selected. Move away from strong electromagnetic fields. |
| Display shows "OL" (Overload). | Measurement exceeds the range of the selected function. | Switch to a higher range if available, or ensure the measurement is within the device's specifications. |
| No NCV detection. | Not close enough to live wire; Wire is shielded. | Ensure the NCV sensor is close to the live wire. Note that shielded wires may not be detected. |
| Screen discoloration/damage. | Physical pressure or impact. | Handle with care. Consider a screen protector if available. |
