Encountering an error while measuring?

Some of our customers have reported encountering an error, specifically an E02 error message, while attempting to measure with our BPM-417. This error indicates that the device has detected motion or that the pulse is too weak during measurement. Movement can adversely affect the accuracy of the measurement, so we recommend taking a moment to relax before attempting to measure again.

If the error persists, we advise removing the batteries for 30 minutes and then replacing them and attempting to measure again. Additionally, we suggest watching our 'How to use' iProven video down below to gain helpful tips on positioning the device correctly. It is crucial to position the device about two fingers above the wrist joint to obtain an accurate reading; otherwise, it will display an error message. The optimal height for the device may vary, but we recommend resting the elbow on a desk and follow the positioning guide sensor. Please note that obtaining accurate measurements may require some patience and fine-tuning. We believe that our device is an excellent tool for monitoring wrist blood pressure.
