Keiser Computer Calibration

Keiser Computer Calibration Tips

  1. To begin, start with the shifter in the down position.
  2. Plug the circuit board wire into the computer.
  3. Plug the battery wire into the computer. Once the battery connection is plugged in the computer will scroll through some random numbers as it is resetting.  Pay close attention to the second row of numbers.  It must read between 30-70 or the computer will never calibrate properly.  If you see a number in this range, proceed to step 4. If not, proceed to step 3. (b).

    (b)  If you are getting a reading below 30, it will result in an error 3 when trying to calibrate the computer.  If you are getting a reading above 70, it will result in an error 4 when trying to calibrate the computer.

    The only way to adjust this number is by moving the gear on the lower circuit board.  You are limited to about 30-40 seconds to make this adjustment and still see the number on the screen.  If the screen goes off before you have properly adjusted the gear, simply reset the computer by unplugging the battery.  Allow it to reset and it will display the numbers again.
  1. Once the computer has completely reset, the screen will be blank.  Turn crank arm one full revolution to wake the computer.  You will see 0:00 in the fourth group of numbers. 
  2. Stop the crank and move the shifter to the 1/2 way point or until the handle appears to be straight up and down and then move the shifter back to the down position.
  3. Turn the crank arm one full revolution or until 0:01 appears in the group of numbers.
  4. Manually, fully engage the lower magnet assembly 6 times.

If done properly, you will see "CAL'b" in the fourth row.  If calibration is unsuccessful, you will get an error code. 

These errors range from 1-4. 

  • ERROR 1:  This error is the result of not moving the shifter far enough to 1/2 way.
  • ERROR 2:  This error is the result of moving the shifter past the 1/2 waypoint.
  • ERROR 3:  This error is seen when the lower circuit board is out of calibration.  See 3. (b)
  • ERROR 4:  This error is seen when the lower circuit board is out of calibration.  See 3. (b)
