What to do if Endress+Hauser Data Loggers show no measured value display and no LED lit?
- KkatherinenormanJul 31, 2025
If your Endress+Hauser Data Logger shows no measured value display and no LED is lit, first, check the supply voltage to ensure it is properly connected. If the supply voltage is connected but the issue persists, it is possible that either the device or the power unit is defective and needs replacement.
