6.4.4 Control parameter
Select " Control" for programming control. (Screen 6.11)
a) Control 1 and control 2:
b) Mean value:
trol.
c) Minimum:
d) Batch number:
e) Select "OK" to confirm the programming or Select "Exit" to go back the
above menu without modifies.

6.4.5 Selecting a Mode

Into the menu of the "Programming" (screen 6.9), click "Change mode". And then
select "Yes", the screen 6.12 appears:
a) Endpoint
After a required incubation time, the reaction reaches its maximum color develop-
ment, or its Endpoint. The color of the reaction will remain stable and constant for
certain period of time. During this time a measurement in Absorbance is taken.
b) Endpoint Bichromatic
Bichromatic is actually endpoint determination measured at two different wave-
lengths. The advantage is that some unwanted interference due to the color of the
serum sample can be eliminated by subtracting the measurement done with the
second wavelength filters. This can be done when you select a sub-wavelength in
"Parameter change" menu. It was described in 6.4.1.
c) Endpoint determination against a standard Curve or against a Multi-
standard Curve
This is a normal endpoint determination, in which linearity may not be perfect
throughout the whole range that is interest. As a result it is calibration curve (a
number of standards) instead of a single standard.
d) Kinetic
Kinetic determination are tests whose enzyme activity is measured continuously
over a certain period of time and finally referred to 1 minute.
e) Two point
After a pre-defined incubation time, two absorbance readings are taken at differ-
ent and programmed time interval. From the delta absorbance between the two
measurements the final result is calculated. Each of the measurements taken is a
mean of a large number of readings taken in quick succession.
6.4.6 Save the Change
After select the measure mode, Select "Save change" to save the selection. The
menu will change to the "test enter" menu. Select "Enter" to perform the test
procedure.
