Why Did My Assessment Fail or Not Complete Successfully?

Common reasons an OTO assessment might fail or not complete, and how to fix them so you get a successful reading.

If your assessment didn’t complete successfully, it’s usually due to a temporary issue with signal quality, connection, or setup. These are common and can typically be resolved with a few quick adjustments.

The most common reasons include:

  • Sensor connection issues
    Your biosensor may not have been properly connected or fully activated before starting the assessment.

  • Low battery
    If the sensor doesn’t have enough charge, it may disconnect during the assessment.

  • Poor belt placement or contact
    If the belt is too loose, too low, or not making consistent contact with your skin, the signal quality may drop.

  • Dry or improperly placed electrodes (DC cables)
    For accurate readings, electrodes should be fresh, properly attached, and slightly moistened.

  • Movement during the assessment
    Small movements, talking, or muscle tension can interfere with the readings.


How to Prevent This

To improve your chances of a successful assessment:

  • Ensure your sensor is fully charged and activated (blue light blinking)

  • Position the belt high on your chest and snug against your skin

  • Heavily wet the electrodes and place them correctly

  • Remain still and relaxed throughout the assessment
