5.4 Measured value recording
For the ion measurement of the media to be examined, they
must first be mixed with the strengthening solution (stock so-
lution, factor 1:50).
The ion electrode is completely immersed in the medium to
be measured at the measuring head. If a number of different
test solutions are to be measured, it is advisable to rinse the
ion electrode with deionized water between two measure-
ments and carefully shake off the water to avoid cross-
contamination of the samples.
5.5 Maintenance and cleaning of the electrode
After use, clean the electrode with deionized water and dry
carefully. Fit the protective cover, but make sure that the low-
er end of the electrode does not rest on the bottom of the
protective cover.
5.6 Replacing the battery
Remove the battery
Open the sensor by turning the screw
cap on the back of the sensor counter-
clockwise, e.g. with a coin.
Fig. 5
Lever the battery sensitively,
e.g. with the help of a small
screwdriver or a small pair of
scissors, out of its socket. In-
sert the screwdriver as shown
in Fig. 6.

Insert new battery
Slide the battery under the golden metal nose (Fig.7-1). Make
sure that the battery is completely under the metal nose and
completely pushed to the upper edge.
Push the battery into the socket
by pressing lightly on the oppo-
site side.
The battery slips under the two
plastic lugs (Fig. 7-2), which is
also noticed by a short "click".

Before closing, make sure that
the seal in the lid is not bent and
lies neatly on the edge of the lid.
Then tighten the cover clock-
wise.
