700 IQ (SW)
If you need to disconnect the sensor from the sensor connection cable,
please note the following points:

Before disconnecting the sensor from the SACIQ (SW) sensor con-
nection cable, remove any larger pieces of contamination from the
sensor, particularly in the area of the plug connection (brush it off in
a bucket of tap water, wash it off with a hose or wipe it off with a
cloth).
 Unscrew the sensor from the SACIQ (SW) sensor connection cable.
 Always place a protective cap on the plug head of the sensor and on
the SACIQ (SW) sensor connection cable so that no moisture or dirt
can get into the contacting surfaces. It is included in the standard
scope of delivery of the SACIQ SW sensor connection cable.
 In corrosive environments, close the socket of the sensor connec-
tion cable with the screwable SACIQ-Plug when it is dry in order to
protect the electrical contacts from corrosion. The protective plug is
available as an accessory (see section 5.3 A
CCESSORIES ).
Cleaning
CAUTION
Acetic acid irritates the eyes and the skin. When han-
dling acetic acid, always wear protective gloves and
protective goggles.
We do not recommend unscrewing the sensor from the
sensor connection cable when cleaning the sensor shaft
and measurement window. Otherwise, moisture and/or dirt
can get into the plug connection where it can cause contact
problems.
NOTICE
The sensor warms up during operation in the air.
Consequently, pollution can collect in the vicinity of
the measurement window due to the evaporation of
liquid. Therefore, avoid any lengthy operation in the
air.
1 Pull the sensor out of the sample.
2 Remove any coarse pollution from the sensor (by brushing it off
in a bucket of tapwater, spraying it off with a hose or wiping with
a cloth).
3 Clean the sensor shaft and the measurement window as
described in the section C
LEANING AGENTS .
4 Then, rinse it thoroughly with tap water.
