Special Notes
7.4.1. This meter build-in below two kinds of calibration solution series, please set up in the
parameters P1;
(a) (Europe & U.S.A. series) — 84μS/cm, 1413μS/cm, 12.88 mS/cm and 111.9 mS/cm
(b) (China series) — 146.6μS/cm, 1408μS/cm, 12.85mS/cm and 111.3 mS/cm
7.4.2. This meter has a unique one-point calibration function, to choose one calibration solution
whose conductivity is close to the test samples. In general the most common calibration
solution is 1413 μS/cm. Use the equipped 2301-S conductivity electrode (K = 1 cm
-1
), and
do calibration with 1413 μS/cm calibration solution, the range can reach up to 100 mS/cm.

7.4.3. The temperature compensation coefficient of the meter setting is 2.00%/℃ by default.
However, the conductivity temperature coefficient is different for different solutions. Users
can refer chart (7-2), as well as the data which they receive from experiments to set in the
parameters setting of P4. At the same time, meter will do automatic non-linear temperature
compensation in the high purified water which less than 10 μ S / cm.
Note: When the coefficient of temperature compensation is set to be 0.00, that is, there is
no temperature compensation when testing, the measuring value is based on current
temperature.
