value must be within the measurement range of the respective submethod, otherwise the
entry will not be adopted). The changed calibration will be stored automatically and will be
executed the next time the concerned method will be chosen. The changed calibration will
be indicated in form of a star behind the respective test name. When stored, the results
measured with an adjusted calibration will be indicated with a star, too. The calibration ad-
justment can be deleted and set back to factory calibration by pressing
The measurement values in the memory will not be affected by the reset.
We recommend to use the factory-provided calibration and not to change this one. The
calibration can be adjusted to meet regulatory requirements. For the calibration adjustment
procedure we recommend to use a standard with a value located in the upper third of the
measurement range to reduce the calibration error to a minimum.
