1. Necessity of calibration: As time goes by and the frequency of use increases, the Manual Sphygmomanometer may have measurement deviations, so it is particularly important to calibrate it regularly. The purpose of calibration is to ensure that the measurement results are accurate and reliable, while increasing user confidence and reducing the risk of misdiagnosis.
2. Calibration cycle: The calibration cycle of the Manual Sphygmomanometer is not clearly specified, but the common recommendation is to calibrate it at least once a year. If it is used frequently or has been purchased for a long time, more frequent calibration may be required, such as once every six months.
3. Calibration method: Calibration of the Manual Sphygmomanometer usually requires the use of professional calibration equipment, so it is best to send the sphygmomanometer to a professional institution for calibration. Some simple calibration methods include comparing with a mercury sphygmomanometer. If the difference between the two measurements is within 5mmHg, the Manual Sphygmomanometer is considered to be calibrated.
4. Calibration steps: The calibration steps include preparing the mercury sphygmomanometer, connecting the calibration kit, simultaneous measurement, data comparison, adjusting the calibration value, and repeating the measurement and adjustment.
5. Notes: During the calibration process, the environment should be quiet and stable to avoid external interference; the calibration should be carried out according to the manual sphygmomanometer instructions; the calibration results should be recorded in detail for future reference.
6. Maintenance: In addition to calibration, the daily maintenance of the manual sphygmomanometer is also very important, including keeping it clean, storing it properly, checking the battery, etc., to ensure the normal operation of the equipment and extend its service life.
7. Professional calibration agency: If an individual cannot complete the calibration, a third-party calibration agency can be selected for calibration. These agencies usually have authoritative professional qualifications such as CNAS and CMA.
