  If your EXFO Measuring Instruments unit doesn't start, it might be because the battery is completely discharged. If the battery level allows, the unit’s LED will blink quickly to indicate the low battery status. Connect the unit to an external power source to recharge the battery. If the battery is no longer charging properly, you may need to replace it.

  Roger CastilloAug 11, 2025
  Your EXFO Measuring Instruments battery may not be recharging because the ambient temperature is too high or too low. Ensure the temperature is within the specified range for recharging. Another cause could be that the USB power adapter is not connected properly. Make sure the USB power adapter is correctly connected to both the unit and the AC outlet. If the problem continues after verifying the connection, the USB power adapter may be defective. Try replacing it; you can purchase new USB power adapters from EXFO.
