When doing so observe the following points:
z
The receptacle for the reference electrode is marked by a recess. It
extends into the inside of the sensor clearly deeper than the other
two receptacles (see Fig. 3-3).
z
The measurement and compensation electrodes can be mounted in
the remaining two receptacles in any order.
z
During installation make sure the area behind the sealing ring of the
electrode and the receptacle are absolutely dry and clean.
z
Plug the electrode on the special socket wrench provided and insert
the electrode with the special socket wrench.
z
Screw until the electrode seats without any gap on the electrode
support. Thus the tightness and electrical contacting are granted.
Note
When mounted, the electrodes can be recognized by the features
described in section 6.3.
3.4.2 Mounting the protective hood
CH cleaning head
(option)
For permanent operation, we recommend to use the CH cleaning head
for compressed air-driven cleaning. It is mounted instead of the
standard protective hood. The compressed air cleaning is started time-
controlled via the IQ S
ENSOR
N
ET
system. Information on the required
components is given in the WTW catalog and on the Internet.
If no CH cleaning head is used the standard protective hood should
always be mounted for measuring. It protects the electrodes from rough
mechanical impact.
