Operation

4.1

Switching on the measuring instrument

1 Connect a conductivity measuring cell to the measuring instru-
ment.
2 Press the <ON/OFF> key.
Display test appears briefly on the display. Subsequently, the
selected cell constants and the temperature compensation that
was set up appear for approx. one second one after the other.
The measuring instrument then switches to the measuring
mode that was last selected.

Measuring

4.2.1 General information

Perform the following preparatory activities when you want to measure:
1 Connect a conductivity measuring cell to the measuring instru-
ment.
2 Set up the correct cell constant for the conductivity measuring
cell (see section 4.3.1).
3 Use <M> to change between the conductivity measuring mode
(
Only carry out measurements with a temperature probe. The tempera-
ture probe is shown on the display by TP.
The WTW TetraCon325 conductivity measuring cell has a temperature
sensor integrated in it.
Note
The conductivity measuring instrument automatically recognizes the
type of the temperature probe used. This enables the measuring cells
to be connected with the NTC30 or Pt1000.
The instrument has a nonlinear temperature compensation that can be
switched off (see section 4.3 C
).
SATION
The reference temperature (Tref) can be switched between 20 °C and
Tref 25 °C. It appears on the display as Tref20 or Tref25. To switch over the
reference temperature, see section 4.4 C
in µ S/cm) or salinity (SAL).
