These procedures must be performed in sequence to identify a fault in the module. Ensure the module has the latest firmware installed before performing these tests.


1. Battery Test

  1. With the free VINC App on an Android phone or tablet, exact battery voltage can be read on the front page, for each crank independently. If you do not have VINC, the following test will determine if the module has sufficient battery power.
  2. Remove the battery cover with 2mm hex key
  3. Remove battery cells and check contact for dirt or damage. Also check that batteries are SR44 not LR44.
  4. Re-install batteries and module cover. Watch the light carefully-
  5. For older cranks, the LED light should begin flashing rapidly, and should be stopped with the magnet touched onto the back of the module. For newer cranks there will just be one quick flash when batteries come into contact. (No magnet swipe is necessary) If lights flash, this indicates there is enough battery to power the cranks.

2. Cadence Test
This procedure tests the cadence sensors for correct functionality.
  1. Trigger the cadence sensor by waving a magnet past the RF cover on the back side of your crank arms and observe the LED light. If the LED light flashes when magnet passes the cover, it has passed the test and works correctly.
  2. If the LED light does not flash when magnet is passed, be sure it is in line with domed cover and in a close proximity. 
  3. If the LED light does not flash after magnet is passed, your Cadence system is faulty. Please create a ticket for additional support.
3. Calibration Test
This is the final test and must only be performed if all other test have been completed and passed. If using o-synce computer follow the below instructions. If using other computers and are unfamiliar with the dashboard please contact your computer supplier directly to insure proper procedures are taken. 
The first step below is essential for ALL calibrations, no matter which head unit is being used!! Use other steps according to your head unit instructions, making sure if there is an automatic zero/calibration function, it is turned OFF.

Go to: Setup > Sport Profiles > Name of profile > Sensors > Power > Calibrate>Manual Zero

STEP 1 - Set up bike for calibration
  • Position crank arms at 12/6 o'clock (vertically)
  • Ensure there is NO load on crank arms 
  • Select calibrate/manual zero on bike computer 

STEP 2 - Press calibrate. Record number displayed.
  • Load the cranks by positioning them horizontally and stand on them or go for a ride and ensure both positive and negative torque is applied.
  • Repeat step 1 above and take another calibration reading. Record results.
STEP 3 - Analysis
  • Download the attached file below.
  • Subtract results of step 1 from the results of step 2 to discover your calibration value. If the results of steps 1 and 2 are more than 20 numbers different please create a ticket for additional support.

To ensure procedure was done properly please repeat steps above to confirm results.
