Assembly
Pouring electrolyte
IMPORTANT
• The membrane at the lower end of the membrane cap and the electrodes at the lower
end of the electrode shaft should not be touched, damaged or brought into contact with
greasy substances! Otherwise the sensor will not work correctly. If this is the case,
replace membrane cap or return the sensor for cleaning the electrodes.
• The gel electrolyte is not toxic and can be easily removed from skin/clothing with water.
NOTE
Carry out the following steps at the washbasin!
Open the electrolyte bottle and screw on the nozzle.
Remove the red cap completely from the nozzle and cut off the end of the nozzle.
Remove the membrane cap and unscrew the membrane cap from the electrode shaft.
Place the spout of the electrolyte bottle vertically on the lower edge at the inside of the
membrane cap without touching the membrane.
Fill the membrane cap with electrolyte uninterruptedly up to the start of the thread; remove the
spout in doing so, but it must always stay in the electrolyte. Only a few, very small bubbles
may form.
Check whether the membrane is completely wetted – the previously white membrane be comes
dark. If required, wait some time. If not successful, repeat the fi lling.
Assembling membrane cap
Locate the electrode shaft vertically onto the fi lled membrane cap and turn until the thread
bites.
Turn the electrode shaft such that the small hole below the hose gasket is pointed to the top.
Slowly screw in the membrane cap by hand up to the stop (do not touch the hose gasket).
The membrane may not bulge caused by the internal pressure because otherwise it becomes
unusable! The excessive electrolyte fl ows out through the small hole below the hose gasket
when screwing together the parts.
Thoroughly rinse the leaked electrolyte from the sensor and your fi ngers ander running water.
Assembling sensor
IMPORTANT
• The sensor must be slowly inserted into or withdrawn from the in-line probe housing!
The membrane could otherwise be damaged.
• Do not touch the in-line probe housing fl ow resistor with the membrane!
• The sensor must be kept wet at all times once commissioned - e.g. the in-line probe
housing must not be allowed to run dry.
Assemble the sensor as described in the operating instructions supplied with the in-line probe
housing.
