What causes reference sensor or LED defective on MAHA Test Equipment?
- KKristin ValentineSep 1, 2025
If your MAHA Test Equipment shows that the reference sensor or LED is defective, first check if the transmitter and receiver are properly installed and screwed in. Also, check if the glasses are soiled and clean them. If the problem persists, turn the master switch off, wait 10 seconds, and then turn it back on. If there's still no improvement, contact service.
