6. Calibration ABL800 FLEX Operator's Manual
General information
Purpose The calibration process determines and checks the accuracy with which the
analyzer measures its parameters. The process is therefore important in ensuring
the reliability of results.
Calibrations are performed using solutions and gases of known concentration, for
each of the measured parameters.
Calibration
programs The following calibrations performed on the analyzer are briefly described below.
(For detailed explanation please refer to the
Reference Manual, chapters 1,2,3. )
Calibration Description
1 point Measures each parameter on one solution and/or gas of known
composition, giving one value per parameter.
Relates the measured values to the theoretical values of a
solution and/or gas of the same composition.
Gives the Drift 1 and status values of the electrode.
2 point Measures each parameter on two different solutions and/or
gases both of known composition, giving two values per
parameter.
Relates the measured values to the theoretical values of
solutions and/or gases of the same composition.
Gives the Drift 1, Drift 2 values and the status or zero point,
sensitivity of the electrodes (two sensitivity values are given
for the Crea B electrode and one for the Crea A electrode of
the ABL8x7 FLEX analyzers).
1 point pH/BG
(the USA only) Measures p CO
2
and p O
2
on one gas mixture of known
composition and pH on a known solution, giving one value per
parameter
Relates the measured values to the theoretical values of a
mixture/solution of the same composition.
Gives the Drift 1 of the electrodes.
tHb Calibrates the spectrophotometer. See tHb calibration in this
chapter.
Calibrations performed automatically at specific intervals selected in the
Calibration Schedule setup (see
Calibration Setup in chapter 3 ) are called
scheduled calibrations.
All calibration results are automatically recorded in the Calibration Log from
which they can be viewed and printed. Refer to
chapter 9: Data Management for
details.
The calibration process and a detailed explanation of the terms are described in the
Reference Manual .
