Image: Troubleshooting guide for common error messages and operational issues.
| Error Display | Cause | Solution |
|---|---|---|
| Err1 | Sensor anomaly | 1. Do not speak or shake your arms before measurement. 2. Empty the air pressure in the cuff when measuring. |
| Err2 | Pulse is not detected | Check the wearing position of the cuff and re-measure it according to the required posture. |
| Err4 | Air deflating before inflating | 1. Check whether there is any blockage in the gas path. 2. Check if the cuff is too tight. |
| Err5 | Air tube blocks before inflating | 1. Whether the cuff air pipe is compressed. 2. Check if the cuff is too loose. |
| Err6 | Strong interference during measuring | Please do not move or speak during the measurement. |
| Err7 | Air pressure more than 300mmHg (40.0kPa) | Whether the cuff air pipe is compressed. |
| No reflection | Low power | 1. Replace batteries timely. 2. Be sure 5V power adapter is 1000mA or more (if using adapter). |
| No inflation | Cuff is leaking | Please contact the after-sale service. |
