There are many natural factors that affect the accuracy of a blood pressure monitor, such as ambient temperature, atmospheric pressure, height and latitud. In addition, after a certain period of use, the influence of the compenents quality and components aging problem should not be neglected.
With this patented automatic correction and calibration technology, each time the OSTAR heart spectrum blood pressure monitor is turned on it performs an internal check of the measurement accurancy according to the surrounding enviromental conditions such as temperature, humidity, air pressure, height , latitude, etc. and its components status. If any difference outside the tolerance of the built-in setting is found, the OSTAR heart spectrum blood pressure monitor will conduct an correction accordingly and calibrates the equipment to re-establish the measurement accuracy.
The automatic correction and calibration technology ensures that every measurement made by OSTAR heart spectrum blood pressure monitor is of the same accurancy, regardless of when and where the measurement is performed.
