In addition to calibration, analysis of quality control material is
required to verify the performance of the EasyStat analyzer. This pro-
cedure is outlined under Analyze QC in this chapter.
The EasyStat analyzer is factory set to perform automatic two-
point calibrations every eight hours. To change the setting, proceed
to the SECOND MENU and select SETUP MENU, then
CONFIGURATION, and CAL FREQUENCY.
A two-point calibration can be interrupted to perform stat samples.
Press NO and STOP CALIBRATION? is displayed. Press
YES and SYSTEM CALIBRATION INTERRUPTED is dis-
played before returning to the HOME MENU for sample analysis.
When the sampler is raised during calibration, the display prompts
you to
RETURN SAMPLER
. When the sampler is returned to
the closed position, the message SYSTEM
CALIBRATION
INTERRUPTED
appears for 10 seconds before returning to the
HOME MENU.
No more than three interruptions are permitted dur-
ing a scheduled calibration.
When an electrode does not calibrate successfully, that parameter will
not appear on the screen. A parameter will not be displayed or print-
ed if PATIENT DATA is turned off under USER OPTIONS
in the SETUP MENU. The reporting of specific analytes is dis-
abled under REPORTED PATIENT DATA. No sample results
(including dependent calculated results) are given for that electrode.
Refer to ELECTRODES in Troubleshooting.
The analyzer will display any error detected during calibration. If an
error occurs, the analyzer will automatically attempt a second two-
point calibration. If this fails, troubleshooting may be required.
During each sample analysis, the EasyStat analyzer performs a one-
point calibration.
