With this option you can reject all the calibration data of an elec-
trode Id. They are then in the same state as before the first cali-
bration (slope = 100%, pH(0) = 7).
Although the electrode Id is retained, it cannot be selected under
PARAMETER pH/measuring parameters/electr.id until it
has been calibrated again.

For each calibration buffer the pH value used and the measured poten-
tial are given. The given value for the pH is taken from the stored series
of buffers of the buffer type selected in the calibration parameters (see
Section 9.4). The pH values for temperatures within the given 5 °C steps
are calculated by linear interpolation.
A buffer which has been deleted by

If at least 2 calibration buffers have been used then the calibration
