denominator becomes zero.
•An overflow occurs in
logarithmic or exponential
calculation.
•In isozyme Q-channel
concentration calculation, the
data alarm of 'calculation
disabled' is indicated for the
isozyme P-channel data or
the isozyme P channel is not
measured.
•Calculation for a calculation
test has been attempted with
the data having a data

mean value ± 2SD in case of a
control sample).

Remedy
•Confirm monthly flow
path washing.
•Replace the diluent and
internal standard
solution.
•Check the data alarm
name and take a proper
measure.
•The data is left blank.
•Prepare appropriate
standard solution.
•The data is left blank.
•Determine the cause of
failure to color
development such as
improper kind of
standard solution, wrong
set position and
clogging of sample
probe.
•Dilute the sample or
reduce its volume and
perform analysis again.
•This alarm is not
indicated for serum
index.
•Correct setting on the
parameter registration
menu 1 screen.
