4. Depending on the values input for (a, b), the
apparent limits of the measurement range
will shift as follows.
(Example) GLU measurements
If a=1 and b=0 (Y=X), the measure-
ment range is 10 to 600 mg/dl. But by
inputting regression coefficients as
shown, the lower limit changes to A
and the upper limit to B.

If the measured data is below the
measurement range, an “@” mark is
added as shown in the example print-
out.
If the measured data is above the
measurement range, a “>” sign is print
-
ed as shown in the example printout.
IMPORTANT:
Reported values with “@” marks
may not be accurate. Run the meas-
urement again.
