Specific operations: select CAL in the menu and put the dry and clean sensor
into the known conductivity buffer solution, press
ENTER
to enter its
program, then the instrument displays the measured value of the solution,
and in flashing mode which is different from the measurement states. After
the measurement data is stable then press
ENTER
again, now only the first
digit flashing in the display data means it is modify bit. Press
DOWN
to
choose the modification bit, press
UP
key to modify the data, make the
display value as same as the conductivity value of the solution, press
ENTER
to store the calibration data(This value is stored even after power
failure), and return to the setting state.

C100—temperature calibration
CDTX-111 has temperature measurement function, for the automatic
temperature compensation, and also can be displayed on the monitor.
Temperature calibration requires a high and a low constant temperature
environment. Such as ice water mixture (0
℃
) and boiling distilled water
(100
℃
). C0 is used to calibrate 0
℃
. select C0 in the menu and put the sensor
into 0
℃
environment, press
ENTER
to store the calibration data
, and
return to the setting state. The Method of calibrate 100
℃
is as same as
calibrate 0
℃
.
