sample test before must first be blank experiment. Method is as follows: take out a
cup into the test cup, and in a grain of stirring, and then select the test cup, such as
"no. 1 cup", touch the selected test cup corresponds to the "quality sample" and with
"increase" and "decrease" button the samples quality is transferred to the "0.000",
then the sample quality department according to "blank", as shown in the figure
below. After press "start" button, the machine will automatically blank experiment
operation, the end of the test instrument to beat blank blank value. (note: to observe
the neutralization liquid titration speed about every drop 1 seconds) and then will
finish cup to take out the blank experiment, experiment. Blank experiment process
with sample determination.

4,
End Hue
: experimental basis of titration end point, is refers to the test at the
end of the value of the color, that is to say, when the current value is greater than or
equal to the finish color color instrument test end, changing the method according to
the finish color below Numbers increase and decrease to change data are stored in
the instrument.
