Blank Measurement
The system uses blank measurements to check cleanliness of the system and
reagents. Run a Blank measurement:
•
Daily once, before sample analysis
•
After any reagent change (activated manually from MEASURE / MEASURE
BLANK menu).
•
After the replacement of any hardware component that is closely related to the
measuring process (aspiration, dilution, counting, rinsing).
In MEASURE mode press the Blank button. If Blank measurement was not
acceptable, press DISCARD to discard blank result or repeat Blank measurement
until the results are acceptable. The analyzer is ready for sample analysis, and
displays an empty sample measurement screen.
There are 3 regions for blank value handling:
1. Optimal – all results are within acceptable ranges.
2. Blank is high – ! flag displayed at relevant results.
3. Blank exceeds acceptability – no results displayed.
Parameter 1. No flag at parameter
2. ! flag at result
3. E (error) flag at result
