MON 1
（ XX Test ）
Calibration monotone
checking error
Nonlinear calibration
curve is not monotone
Recalibrate
COV 0
Iterative but not
convergent while
calculating the
calibration parameter
or result！
When calculating
nonlinear calibration
result, if no qualified
result is obtained after
1000 iterations,
calibration is failed
Rerun
R！
0
（ Nonlinear
calibration test） The
response of sample
or control out of
response range of the
calibrator
Abnormal sample
(hemolysis, etc).
Calibrator concentration
is too low
Run diluted sample, or
recalibrate
PR1 1 Printer can not print
Not enough paper in the
printer, printer error or
printer not connected
Check whether there is
enough paper. Restart the
printer or replace the printer.
PR2 1
Thernal printer can
not print
Not enough paper in the
printer, printer error.
Check whether there is
enough paper or replace the
printer.
PR3 1 No printing template No printing template Upgrade printing template
ABS 0
The absorbance of
sample, calibrator or
control exceeds limit
Absorbance exceeds
the limit
Check whether the sample is
qualified; whether the
reagent expired; whether the
cuvettes are dirty; whether
the flow cell is placed right.
ABS++
1
The absorbance of
water blank, reagent
blank or sample blank
out of readable range:
-5000-35000
Bubble in the cuvette or
else
Remove the bubbles; rerun
ABS+ 0
The absorbance of
XX test out of
readable range. (only
for sample, calibration
and QC test)
Bubble in the cuvette or
else
Check the position of the
flow cell and whether the
optical system is normal.
RBK 1
（XX Test）Reagent
blank out of range
Reagent expired or dirty
cuvette
Rerun after replacing
reagent
NLN-1 1
（ XX Test ） （ xx
sample or calibrator
or control ） The
reaction curve has no
linear interval
Measuring points in
both kinetic read
window and substrate
limit are less than 3
Rerun or rerun after dilution
NLN-2 0
（ XX Test ） （ xx
sample or calibrator
or control ） The
Measuring points in
both kinetic read
window and substrate
Rerun or rerun after dilution
