Calibration

Every MP has a certain measurement error. To reduce it, a sensor is calibrated using a reference sensor that is an order of magnitude more accurate than the calibrated sensor.

During the calibration the sensor error is measured that can be used to correct its readings. This measurement error is stated on a sensor calibration certificate and shall be entered into MP “New Adjustment Value” field. After saving it is shown in “Current Adjustment Value” field.

There is also “Calibration interval” which defines the calibration certificate validity period in months. The default setting is 12 months but can be modified if needed.

The calibration related MP fields are described in Common MP parameters.

The adjustment value is used to adjust the measurement received from the sensor. The system stores the adjusted reading which reduces the measurement error.

All the system MPs must have valid calibration certificates. There is a dedicated Calibration menu to manage the MPs calibration certificates.

The calibration can be done automatically using ICU Scandinavia calibration service. The ICU Scandinavia calibration service is performed using dedicated reference sensors and an Android app that controls the calibration process. It is described in a separate manual.

A user can also manually add adjustment values from a third party certificate as described in Set calibration adjustment manually.

Calibration certificates can be stored in the system.
