5.7.2 Deleting the user-specific calibration
The user-specific calibration can be deleted only for those
methods with which this can be used.
Call up the method in question, e.g. [3] [8] [0]
[Enter].
In the case of methods with a countdown function, skip this
function by pressing the [Enter] key twice.
The display now shows:
If a prompt for zero calibration appears, press the keys
[Mode] [4] [6] in succession.
Confirm by pressing [Enter].
The display now shows:
Pressing the [1] key deletes the user-specific calibration.
The original factory calibration is reactivated.
Pressing the [0] key retains the user-specific calibration for
further use.
The instrument then returns to the countdown mode or,
respectively, in the case of methods without a countdown
function, to the zero-calibration prompt.
