Calibration
The user may execute manual or set automatic calibration cycles at user defined intervals. In
the auto mode the analyzer calibrates periodically and checks the validity of the calibration per
the specified tolerance for the REFERENCE slope and offset parameters. New calibration data
is only accepted if it is within the limits of the specified tolerance for the REFERENCE
calibration parameters. The current column shows the current operating parameters that are
used to calculate the sample concentration.
Cleaning
Automatic flushing of the reaction cell may be programmed.
The default setup for the analyzer uses the sample as the cleaning solution. A cleaning cycle
can be performed by pressing:
STOP
➔
MENU
➔
MEASUREMENT
➔
CLEAN
This cycle helps maintain clean reaction cell.
NOTE:
To avoid damage and contamination to the reaction cell, use only cleaning
solutions recommended by the factory.
Post Wash
Automatic post wash cycles are typically part of every measurement cycle. At the end of the
analysis, the post wash cycle evacuates the reacted sample from the cell and cleans it to
minimize coating and residue deposits in the cell. The post wash cycle settings can be
accessed from the ANALYSIS PARAMETERS menu:

Please consult factory before modifying any of the parameters.
Priming
Priming of the instrument lines may be done as auto (all the solutions) or manually by selecting
the specific reagent or standard. Priming fills the tubing, purges the lines of air, and prepares
the analyzer for measurement mode.
The PRIME VOLUME in mL applies to all the listed solutions in the priming menu.
