The test limit of Calibration Factor Deviation test is only valid when the power sensor operates within the temperature range of 25 °C ± 10 °C. |
In this functional test the calibration factor data is read from the EEPROM of the power sensor, then compared to the measured calibration factor from the Calibration Factor test performed. The difference between the original and measured calibration factors shows how much the calibration factor has deviated since the last calibration.
As the specified maximum uncertainty is a relative uncertainty, the deviation will be computed as relative to the original calibration factor.
None required.
