What is the significance of calibrating your Elpis wearable ...
All Elpis advanced technology devices require some degree of calibration for an accurate heart rate, blood oxygen, blood pressure and ECG reading.
Calibration is important as it enables the user to have some degree of confidence in the results that they are monitoring and recording, and in some cases, controlling or regulating the treatment from the results of their measurements.
Calibration is the activity of checking by comparison with a standard. For the blood pressure readings in Elpis it may be compared against a medical-grade blood pressure cuff. It can also include adjustment of the instrument to bring it into alignment with a known standard.
The purpose of calibrating is to ensure that a measuring device is accurate, reliable and consistent as the measurements may be used in a decision-making process. Data read or collected should be reasonably accurate within acceptable ranges. Conclusions based on errors can result in negative consequences from the decision made.
There are three main reasons for having instruments calibrated:
- To ensure readings from an instrument are consistent with other measurements
- To determine the accuracy of the instrument readings.
- To establish the reliability of the instrument, so it can be trusted.
Calibration is intended to eliminate or reduce any bias in an instrument’s reading over a range of continuous values. Since every individual has different reference values, calibration is a way to reduce this bias to achieve a standard.
All instruments need calibration over a time period, due to wear and tear, age and environmental conditions.
