“STD" and
“SETUP” button is on the right of
screen.
When last calibration is multi-calibrating, user can press “<= =>”(moving) button to display detailed
data of each standard buffer solution under each point.
At this time, press “STD” button to calibrate electrode slope directly. (see calibration item for
specific procedure)
Press “X”(exit) to exit viewing mode, the meter is back to starting working state.
Press “SETUP” button to set new standard buffer solution group.
5.2 Setting standard buffer solution group
The meter has automatic distinguishing function, which can distinguish 10 different standard
buffer solutions. Multi-point (not exceed 5 point) calibration is applicable. In order to ensure the
accuracy of the measurement, user should set up corresponding standard buffer solution group,
to avoid range of pH value overlapping. Otherwise the meter will not distinguish different kinds
of standard buffer solution, which will influence the result of calibration or even give you wrong
information.
For example, when user adopt 4.008pH
、
9.180pH standard buffer solution to calibrate slope of
electrode, you can set standard buffer solution group as 4.008pH & 9.180pH. In actual calibration,
the meter is able to distinguish these two kinds of standard buffer solution automatically.
Press “SETUP” button to enter setting current standard buffer solution mode. Please refer to
diagram 9.
