Tolerance band recorder
(Diagnostics/Module PH 3400-xxx)
Records the tolerance ranges for zero
and slope over the time. New calibra-
tion values are only accepted if the
tolerance limits have been exceeded.

Tolerance band recorder
(For adjusting the tolerance band, see next page.)
During manual calibration this function checks the zero and slope values and
automatically performs an adjustment when the tolerance band is exceeded.
The parameters are stored in the tolerance band recorder (Diagnostics menu).
If the zero and slope values determined during calibration remain within their
tolerance bands, the new data are not saved.
Drift due to aging or calibration scatter can be identified at a glance, thus
allowing to draw conclusions as to electrode life and the required calibration
interval.
In the Calibration record you see whether the data have been saved or
whether the old data can still be tolerated.
