4.6 Heart Rate Function Issues
Symptom:
Heart rate function does not work or is reading incorrectly
Solution:
1. With a multi-meter set for DC voltage, place one terminal on each of the HR grip plates. The HR grip should give a
voltage reading of between 0.5 and 2.0VDC. If the voltage is not between 0.5 and 2.0VDC, remove the 3 screws holding
the HR grip together and check the connection of the HR grip wiring.
2. Check continuity of the HR grip wiring. Place one terminal of a multi-meter set for resistance on the HR grip wiring at the
HR grip, and the other terminal on the HR grip wiring at the console. The multi-meter should register an ohm reading of
around 1. If the reading is higher than 1, replace the HR grip wiring.
3. Remove the console. Remove the 6 screws holding the front of the console to the rear. Check the connection of the
HR board wiring to the UCB. If all the wiring is intact and has good contact, replace the HR board.
4. If the HR board, HR grips, and HR grip wiring do not solve the issue, replace the UCB.
