Note to the users of the ABL90 FLEX analyzer
This note to users outlines the most significant changes and improvements of software
version 2.4 in the English version of the ABL90 FLEX reference manual (994-527).
Changes/Description
CHAPTER 3:
Calibration pCO2, cGlu, cLac calibration
With the warm start feature in software version 2.4, the last
sentence in this section: When a new sensor cassette is installed,
the sensitivity calibration is performed more frequently" is not
necessarily true and should, therefore, be ignored. The text
should, therefore, be as follows:
pCO2, cGlu, cLac are sensitivity calibrated on CAL3 and status
calibrated on CAL1. For further information on the pCO2, cGlu,
cLac calibration, see Calibration of the pCO2sensor in section
pCO2sensor and Calibration of the metabolite sensors, in section
Metabolite sensors in chapter 5 in this manual. pCO2, cGlu, cLac
are sensitivity calibrated every four hour and status calibrated
with every measurement.
CHAPTER 5:
Calibration Sensitivity, Definition.
In the table with the sensitivity range limits, the pO2max %
value has been changed from 105 to 110%.
The sensitivities are range checked:
pH
pCO2pO2cK+cNa+cCa2+
cCl–cGlu cLac
% % % % % % % pA/mmol/L pA/mmol/L
Min. 85 60 85 85 85 85 75 100 100
Max. 105 105 110 105 105 105 105 2000 2000
CHAPTER 7:
Interference tests For ClO4– ,interference on cK+(4 mmol/L level), cCa2+ (1.25
mmol/L level), and cCl(110 mmol/L level) has been detected for
test concentration 1.5 mM and the other test concentration levels
should be ignored. The new interference results are, thereafter,
as follows:
Interference on....Substance Test con-
centration cK+
(4 mM
level)
cNa+
(140
mM
level)
cCa2+
(1.25
mM
level)
cCl-
(105
mM
level)
Test
matrix
Perchlorate
(ClO4-)
1.5 mM 0.3 - 0.27* 4-30 Plasma
* Depending on the pH level
A "-" indicates that interference has not been measured on the respective parameter.

CHAPTER 10:
As a manual conditioning of the sensor cassette pack is not
possible for the time being, references to this option are no longer
valid and, therefore, the following analyzer messages no longer
exist in software version 2.4:
972 Sensor conditioning due
1080 Installed sensor cassette was not registered as conditioned
1333 Sensor conditioning started, no BC
Conditioning in
sensor cassette pack
not possible
1334 Sensor conditioning started, BC
Warm start With the new warm start feature in software version 2.4 the
following new analyzer message has been included:
No. Message Interpretation Operator action
1340 Sensor cassette
maintenance by
Analyzer has
been interrupted
This message is used in the Activity
log to indicate startup using a sensor
cassette which has been left without
an FTC activity for more than 1 hour.
No action required
TABLE OF CONTENTS/INDEX:
Conditioning in
sensor cassette pack
not possible
As the pack with the sensor cassette cannot be used for
conditioning, the name of the pack has been changed from
Conditioning unit to Sensor cassette pack.
The manual will be updated with the above information as part of the next manual
update.
Please place this note to the users in the binder of your manual.
