(a) Statitical calculation is made for the result data of routine samples.
(b) Specify Precision Check on the MAINTENANCE screen.
(c) Statistical data for a maximum number of samples is calculated. Up to forty tests
including ISE assay are applicable.

(e) The result data is read from FD.
(f) The result data provided with an alarm is excluded from calculation (also not
counted for N). Note that reference value range over and overflow are excluded
from alarm.
(g) Statistics are not output for unmeasured tests and subsequent tests are placed
close.
(h) When N < 2, statistical calculation is not carried out.
