The following additional parameters are checked:
Sensitivity
Status
In case of error in a scheduled calibration, a new calibration is automatically
performed.
A 1-point calibration is automatically performed with every measurement.
For
pO
2
, which is only calibrated in one point, a calibration check is performed.
If this check fails, a new calibration is automatically performed after
measurement and used to calculate the
pO
2
in the measurement, or, in other
words, actually, to perform a calibration/to ensure a valid calibration.
After sensor replacement, the metabolite sensors have a significant drift in the
sensitivity. The analyzer automatically compensates for this by performing a
calibration, when needed, after every measurement that is used to calculate the
measured metabolite values.
By performing the calibration with the measurement, instead of performing
frequent calibrations, sensor drifts are reduced more effectively. As calibrations,
furthermore, only are performed when needed, the uptime, where the analyzer
is ready for measurement, is maximized.
