7.1.2.2 First Calibration Point
Two options are available for the First Calibration Point:
Point
and
Offset
.
If
Point
option is selected, the slope values adjacent to the calibration points will be reevaluated
(normal calibration).
If at least a two-point calibration has been performed and an offset correction is needed,
perform a one-point calibration using the
Offset
option. The existing slope values will not be
changed.
7.1.2.3 Edit Custom Buffers
If you wish to use buffers other than the standard ones, the Edit Custom Buffers option is
available, allowing you to set the desired pH buffers. Up to five pH custom buffers can be set.
Note: Custom buffers are not temperature compensated. The value of the buffer at the
calibration temperature should be entered. The standard buffers are automatically
temperature compensated.
