6.4.2. This meter has an unique one-point calibration function, to choose one calibration
solution based on the principle of the water samples and calibration solution
conductivity as close as possible, in general the most common calibration solution is
1413 μS/cm. Use the equipped DJS-1 conductivity electrode (K=1), and do calibrate
with 1413 μS/cm calibration solution, can use within the range of less than 100 mS/cm.
Please choose refer to the chart (6-1).

6.4.3. There are two kinds of method which are standard solution calibration method and
constant calibration method for conductivity electrode calibration which have been set
in meter, the statement in item 6.2.
“
electrode calibration
”
is the standard calibration
method, and when the accuracy of standard solution is accurate then suggest the
standard solution calibration method is priority selected, it can ensure the best
accuracy. If user used to use constant calibration method, it can be set according to the
constant on the conductance electrode
（
The new conductance electrode manufacturers
have been standard accurate, customers can be used at ease, such as long-term no use
or fouling. In order to ensure accuracy, first clean up the electrode and then calibrate
