Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try these tips.
-
Reapply moisture to the electrodes and contact patch.
You can use water, saliva, or electrode gel.
- Tighten the strap on your chest.
- Warm up for 5–10 minutes.
- Wash the strap after every seven uses (Caring for the Heart Rate Monitor).
-
Wear a cotton shirt or wet your shirt if suitable for your activity.
Synthetic fabrics that rub or flap against the heart rate monitor can create static electricity that interferes with heart rate signals.
-
Move away from sources that can interfere with your heart rate monitor.
Sources of interference may include strong electromagnetic fields, some 2.4 GHz wireless sensors, high-voltage power lines, electric motors, ovens, microwave ovens, 2.4 GHz cordless phones, and wireless LAN access points.
