Calibration Override
Introduction
The Calibration Override option allows the system to override a failed calibration and obtain results
based on the failed calibration factors.
Calibration Override is available only when an attempt to
calibrate the chemistries has been previously made and failed, the status Cal Failed is shown. A
chemistry with any other status, including Cal Required , cannot be overridden. The calibration can
be overridden while the system status is Standby, Disabled or Running .
IMPORTANT
Overriding a calibration is not usually justified. However, there may be an emergency situation
when a delay caused by calibration is unacceptable to the laboratory. The magnitude of error which is
deemed acceptable when overriding a failed calibration is totally under the control of the laboratory.
Therefore, the Override function should be used with caution.
Override a Calibration
1
Select
Rgts/Cal
from the menu bar.
2
Select the Chem position to override.
3
Select
Options F6
.
4
Select
Calibration override
from the pull-down menu.
Remove Cal Overridden Status
The Cal Overridden status can only be removed by successfully recalibrating the chemistry or by
selecting Chem Bypass. A flag indicating that a particular chemistry has been overridden will
appear in the Instrument Code area on the appropriate Summary or Patient Chartable Results
report. Although a Cal Overridden status can be bypassed, the Cal Overridden flag is only removed
by a successful calibration.
