If the value of electronic sphygmomanometer is suspected to be inaccurate, it can be compared with the value measured by mercury sphygmomanometer. If the difference is greater than 20 mmHg, it can be determined that the value is inaccurate. Go to the place of purchase or contact the manufacturer for calibration.
Pay attention to the tightness of the cuff when measuring blood pressure. It is advisable that the cuff can extend into the tightness of two fingers after fixation. When comparing with the value of mercury sphygmomanometer, we should pay attention to measuring the blood pressure of the same upper arm.

Extended data:
When using Omron sphygmomanometer to measure blood pressure, you need to pay attention to these matters: measure it on 1 three times in the morning, feel comfortable when you get up in the morning, urinate for a few minutes, and avoid the following measurements before and after exercise, within 3 hours after meals, before and after drinking, coffee and black tea, before and after bathing, and before and after smoking.
Take a few deep breaths before measurement, relax, avoid repeated measurement, sit in a chair and keep your back straight. Omron sphygmomanometer can keep accurate measurement values for a long time during use, but it is normal that there will be slight deviation with the increase of use time.
