4.3.2.3 CC—auto/manual temperature compensation switch
CDTX-111 has Auto and manual temperature compensation function. The
user can select between two modes of compensation by the CC in the menu.
Press
ENTER
into CC and display CC0 or CC1. CC0 is Auto temperature
compensation, CC1 is manual temperature compensation. Press
UP
to
switch it, then press
ENTER
to store and return to the setting state.
4.3.2.4 C1-C—set temperature compensation coefficient
The temperature compensation coefficient is different for each type of
solution, so the temperature compensation coefficient is designed to be
adjustable (25°C as the reference), and the range is 0~±10%. Select
C1-C in the menu, press
ENTER
into i
t and display the original value, use
DOWN
and
UP
to modify it, then press
ENTER
to store and return to
the setting state. The temperature compensation coefficient works both in
automatic and manual temperature compensation.
The Calculation Method of coefficient
Remark cond.25=the conductivity value at t=25°C
cond.35=the conductivity value at t=35°C
4.3.2.5 CH—set manual temperature
In this mode the instrument should be set with the “CC1” and the user
