- Check if the power cable is securely connected to both the tester and the power outlet.
- Ensure the power switch on the rear panel is in the 'ON' position.
- Verify that the power outlet is functional by testing it with another device.
6.2 Incorrect Readings
- Ensure battery connection cables are correctly attached with proper polarity (red to positive, black to negative).
- Check for loose connections at both the battery and the tester's output port.
- Verify that the test parameters (voltage, current) are set correctly according to the battery specifications.
6.3 Tester Overheating
- Ensure the tester is placed in a well-ventilated area.
- Check that the cooling vents on the rear are not blocked.
- Reduce the test current if possible, especially during prolonged discharge cycles.
