Why is my Crivit Heart Rate Monitor not showing heart rate correctly?

  Laura Harris DVMAug 2, 2025
  If your Crivit Heart Rate Monitor isn't displaying your heart rate accurately, there are several potential reasons: * Ensure the chest belt is correctly positioned and fits snugly. * Your skin shouldn't be too dry or cold; moisten the contact areas slightly. * Electromagnetic interference or other heart rate devices (within 2m) may interfere. * The distance between the watch and chest belt must be under 70cm. * Wireless bicycle computers may also cause interference. * The batteries in the device might be low and need replacement.
