3.3.2.6 Setting up Correlation Factors
Correlation factors let you correlate results from
your OPTI CCA-TS to other Blood Analyzers.
Correlation factors are available for pH, PCO

, PO

,
Na
+
, K
+
, Ca
++
, Cl
-
, Glu, BUN (urea), Lac, tHb, and
SO

.
NOTE: Slope is a multiplicative factor and Offset
is an additive factor, using the following
formula:
Correlated value = Raw value * slope +
offset.
1. From the <Ready> display, select
<System Manager> and <Setup>.
2. In the <System Setup> menu, press
<Correlation> (Fig. 3-27).
3. Select the numbers you want to change by
pressing (Fig. 3-28). Enter the new
numbers.
4. Press <Factors 2> to go to the next screen
(Fig. 3-29).
5. When entering the actual offset value, select
whether it is an additive or subtractive value
using the +/- keys.
NOTE: The factory setting is 1.0(00) for all slopes
and 0.0(00) for the offsets. This deactivates
the correlation factors.
6. Continue through the other parameters, setting
their correlation factors as above.
7. Press to accept the changes.
8. Press to return to the <Setup> screen
or
to return to <Ready>.
CAUTION:
Since altering the correlation factors
will alter your measurement results,
be very careful to enter the correct
values and conrm the settings by
running at least 10 comparison
measurements between the OPTI
CCA-TS and the instrument to which
it is to be correlated.
