Why Dräger DrugTest 5000 Measuring Instruments screen is not displaying anything?
- Kkevin22Aug 26, 2025
If the screen on your Dräger Measuring Instruments doesn't turn on within 10 seconds of switching it on, it could be because the battery is discharged and no external power supply is connected. Connect the battery charging power supply unit and ensure it's connected to a mains power supply.
