Measurement methods:
1. Tie the sphygmomanometer to your wrist as shown in the picture, paying attention to the position.
2. In order to measure more accurately, please tie the wrist strap tightly.

4. Click the switch, keep the wristband at the same level as the heart, and don't move or talk.
The error code represents:
Er 1: Due to rapid air leakage or weak pulse signal (please check the wrist strap, tie it up, and test again)
Er 2: Due to noise (please do not move or speak, first clear the air pressure inside the cuff)
Er 3: Abnormal blood pressure. (Please check the position of the cuff and re measure according to the standard posture)
Er P: Unable to apply pressure or pressure too fast. (Check if the cuffs are too tight or loose, check if the trachea is blocked)
HI: Displayed in the low-pressure area, indicating that the pressure exceeds the limit. (Measure again in standard posture, do not move or speak)
Troubleshooting:
1.If there is no display on the screen when the on/off button is pressed, please confirm if the battery is new.
2. If it is impossible to measure or the reading is too high, please re measure with the correct posture
3.If the measured blood pressure is abnormally high or low, please wear a wristband correctly, relax, and then re measure. During the measurement process, please remain quiet and do not speak.
4. If pressing the ON/OFF button the pressure is not applied but the reading still appears, please turn off the sphygmomanometer first and then turn on the measurement.
5.If the blood pressure measured each time is different and the reading is too high or too low, please relax first. Because in a tense state, the results of each measurement will constantly change, it is recommended to take a deep breath and calm down before taking the measurement.
