Display: LCD digital display screen  Measurement range: blood pressure 0~280mmHg pulse 40~199 times / min 
Compression method: automatic pressurizing pump  Reducing the way: solenoid valve control pressure  Measurement error: blood pressure + 3% heart rate + 5%  Memory capacity: 90 sets of measurement data and time  Pressure sensing: semiconductor pressure sensor 
Power supply: 2 AAA battery Measurement interval: 1mmHgOperating temperature and humidity: ~+40 C +10 C /40%~85%R.H. Preservation of temperature and humidity: +50 C15%~90%R.H.Weight200gNotes:The wristtype electronic sphygmomanometer is sensitive, so it is necessary to maintain a correct sitting posture during the measurement process. 
After 5-10 minutes of rest, keep breathing evenly, and the measurement site and the heart site should be at the same level. 
Usually, the measurement of the wrist is higher than the measurement of the heart, which results in a lower blood pressure value and a lower level than the heart.
