Note that linearity check is
not carried out in the
following cases.
• The number of
photometric points in the
reaction limit level range
is three or less.

S1ABS? H (Photometry assay) (Note 1)
In calibration, the mean value
of two measured absorbance
values of STD (1) is not
within the specified standard
1 absorbance range (input
value).
Value is absorbance with
End-point Assay, in the case
of late assay, is main wave O
length first absorbance.
• Prepare the standard
properly.
• Set the standard
properly.
• Unless check is desired,
input a value within
- 32000 to 32000 for
"standard 1 absorbance
range" on the parameter
registration menu 1
screen.
Duplicate error DUP U (Photometry assay)
In calibration, this error is
indicated if the difference in
absorbance (or absorbance
change rate) between the first
and second measurements of
STD (i) is larger than the
DUPLICATE LIMIT (input
value).
(i = 1 to N: N indicates the
number of standards.)
• Replace the seal piece
of pipettor.
• Check fastening of
joints.
• Unless check is desired,
input 32000 for
"duplicate limit
absorbance" on the
parameter registration
menu 1 screen.
