16 Reagent Locking
Reagent locking is a commercial feature of the ‘ELite 5’ ensuring that only manufacturer
recommended and approved reagents are used with the analyzer. This way analyzer
performance cannot be impaired by incompatible reagents. All necessary hardware and
software elements are installed and configured on each ‘ELite 5’ unit individually.
Each Erba•Lyse 5P reagent bottle comes
with a reagent key. The key is in a plastic
bag glued to the tear-open flap of the
cardboard box container. Each key
contains license for 800 measurements.
With active ‘reagent lock’ there is an
administrative limit of measurements run
on the ‘ELite 5’. The ‘ELite 5’ keeps track
of the number of measurements
performed. If the limit is reached, then the
‘ELite 5’ will first warn the user about the
fact, then it will refuse to perform further
measurements.
The analyzer decreases the number of available measurements with each sample run, even
Blank, Calibration and QC measurements. When the counter
decreases below 50, and any sample run is started, the user
will receive a warning message about this counter
decreasing. When the number available reaches zero, the
analyzer will not run more samples.
To increase the number of ‘remaining’ measurements, you
have to upload measurement licenses from the hardware-key
to the ‘ELite 5’. The uploading can be initiated during ’Lyse’
reagent level reset. See chapter 14.3.
The hardware-key is similar to a USB memory device but it is
not a real USB memory device. Do not insert it into a USB
connector. (The hardware key will not harm USB ports
however it can’t be predicted how the USB drivers react if a
hardware-key is connected as USB device).
To transfer measurement licenses to the ‘ELite 5’:
- Remove the hardware key from its protective packaging.
- Insert the hardware-key into the HK-connector on the
right side of instrument (see chapter 4.2.5);
- Initiate ‘Reset’ of ‘Lyse’ reagent and follow instructions on the screen;
- All (800) measurement licenses will be transferred from the key to the analyzer.
- Remove the hardware-key from the ‘ELite 5’.
Any already used (empty) hardware key cannot be used again.
- Collect and return them to your dealer/ service personnel/ sales representative for re-
cycling or dispose them as electronic waste adhering local regulations.
