The Encoder Measures Eccentric Reps Instead of Concentric Reps

This means the encoder is in DOWN mode. Change it back to UP mode by following these steps:

 

  1. Power on the unit.
  2. Perform three repetitions by pulling the tether with your hand (ensure to complete exactly three repetitions).
  3. Press and hold the right button (located below the screen) for eight seconds.
