The calibration data of the equipment and the program verification data are compared every time verification equipment is connected in order to secure that verification data is updated if the calibration data of the equipment have been changed. For instance, this can be due to recalibration of verification equipment. Calibration data of the verification equipment can be maintained by changing verification data in the program METERTOOL HCW and clicking on “Write” these new data to the equipment. In order to avoid unintentional change of calibration data ”Write” is protected by a password, which can be obtained from Kamstrup A/S.Calibration data include test points, permissible error, uncertainty, ambient temperature (fixed value) and number of integrations per test.Having entered verification data, the program automatically calculates the true k-factor in accordance with the formula of EN 1434 and OIML R75:2002.
