Description
(1) In calibration, the
STD absorbance data
is indicated with
alarm.
(2) In calibration, data
calculation is
disabled.
<<ISE assay>>
(1) In calibration, the
potential data of
standard or internal
standard solution is
indicated with ADC
error, insufficient
sample alarm, noise
alarm or level alarm.
(2) In calibration, data
calculation is
disabled.
(The result of calibration
is not updated nor saved
onto FD.)
The factor value 'K'
determined in calibration
differs from the previous
value by more than ±20%.
<<ISE assay>>
The calibrator
concentration value and
slope value determined in
calibration differ from the
previous values by more
than the compensation
limit (%).
in multi-point calibration is
larger than the SD limit
(input value).

•Check the
concentration
parameter.
