Precor 9.27, 9.23 manual Troubleshooting Heart Rate Issues, Erratic heart rate readings

Troubleshooting Heart Rate Issues

The following chart may help you understand and troubleshoot erratic heart rate readings.

Note: The following chart does not apply to the 9.23 treadmill where it concerns the chest strap since the chest strap is only available on the 9.27. A heart rate is detectable when the Precor heart rate receiver is properly installed in the display and the unit is turned ON. The touch-sensitive grips are available on both models.

Note: To conduct electrical impulses from a user’s heart, the electrode strips on the chest strap must be in contact with the user’s skin. Usually, the concentration of salts in a person’s perspiration provides enough conductivity to transmit a signal to the receiver in the display console. However, because of body chemistry or erratic heartbeats, some people cannot use the heart rate feature.
