3.1.1. Curve fitting mode: there are first order fitting, first order fitting through
zero, and second order fitting.
3.1.2.
Curve building method: there are standard sample method and coefficient
method. Stand sample method is to
prepare sample first , build curve, and then
test sample. Coefficient method is to enter the known coefficient and build
standard curve, then to test sample.
3.1.3. The number of samples: at least 2 samples. More sample numbers, more
accurate testing data.
3.1.4. Concentration units: Enter the concentration value of each standard
sample, because the parameters of the curve has established limits, please
select the appropriate concentration units.
3.1.5. Wavelength value is required.
3.2. Standard sample measuring
Put various standard samples into cuvette holder orderly, and enter the
concentration value of each sample, then press [enter] key, read the
absorbance of the sample. The input is completed, the data of the standard
sample is calculated automatically according to the parameters of the curve,
displayed on the screen. If the parameter is wrong, then the buzzer alarm, exit
to establish the curve function.
