1. Temperature:
The ideal ambient temperature for calibrating an electronic sphygmomanometer is usually between 18℃ and 25℃.
This temperature range is close to the normal physiological temperature of the human body, which helps to ensure the accuracy and stability of the sphygmomanometer during the measurement process.
When the ambient temperature is too high or too low, it may affect the performance of the sensor and circuit of the electronic sphygmomanometer, resulting in deviations in the measurement results.
2. Humidity:
The ambient humidity should generally be kept in the range of 40% to 60%.
Appropriate humidity helps maintain the normal performance of electronic components, prevents problems such as circuit short circuits due to excessive humidity or static electricity due to low humidity, which in turn affects the calibration and measurement results of the sphygmomanometer.
3. Air pressure:
The air pressure of the calibration environment should be stable and close to the standard atmospheric pressure (about 101.325kPa).
Although electronic sphygmomanometers usually have a certain air pressure compensation function, large air pressure changes may still have a slight impact on the measurement results.
4. Others:
The calibration environment should be kept clean and quiet, and avoid calibration near strong electromagnetic fields to prevent external interference from affecting the normal operation of the sphygmomanometer.
In addition, the equipment and tools used for calibration also need to be regularly inspected and calibrated to ensure their accuracy and reliability.
