If ferrites do not correct the problem, it may be necessary to disconnect the Y cables from your recorder, and
not record servo positions. This would be an extreme case, however. Note that if you have to take this step, it is necessary
to power the recorder from a separate backup battery as described below.
Issue: RPM is not working correctly
Solutions:
•
Make sure you have the writing on the RPM sensor facing away from the red lined side of the magnets.
•
Make sure that under Choose What to Log in the app, you have checked RPM.
•
Make sure that the parameters in the Calibrate Speed to RPM in the app are set up correctly.
•
Make sure that the RPM sensor is plugged into the correct slot on the recorder (should be the bottom slot next to the temp
sensors).
•
Connect the recorder to the computer and launch the app. Then, choose Tools->Live Mode. Make sure that the RPM gauge
is displayed, and spin the magnets, or wave the magnets by hand in front of the sensor. Try both sides of the magnets and
both sides of the sensor. See if the RPM reading jumps.
Issue: The recorder seems to stop recording mid-race.
Solution: The recorder shuts off if it detects a very low battery for an extended period of time. Download the race data, and if you
see the battery voltage is below 4.3 volts constantly, the recorder likely shut off. Charge or replace your battery, or if the problem
persists, install the optional battery backup harness. Also, if you have the recorder set up to pause when its buffer is full, and the
buffer becomes full during your run, the recorder will stop recording.
