It is essential that you relax and squeeze your muscles as
prompted during the first two repetitions of the session.
PeriCoach needs to determine your resting force while your
muscles are relaxed. This process is called calibration. You will see
a Calibrating message during the first two repetitions while this
occurs.
If you get an alert (shown below) that the sensors are having trouble
sensing muscle movement, you will need to try to calibrate again. Press
Restart. If you keep receiving this message, you may be having difficulty
fully relaxing your muscles, or your strength may not be high enough to
register on the sensors.
