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. The sensor will not otherwise
work correctly. If this occurs, install a new membrane cap
or return to ProMinent to have the electrodes cleaned.
• The electrolyte gel is non-toxic and is easily removed from
skin/clothing using water.
NOTE
Carry out the following steps at a washbasin!
Open the electrolyte bottle (included with sensor) and screw on the nozzle.
Remove the red cap completely from the nozzle and flip up the end of the
nozzle to open.
Pull off the protective cover and unscrew the membrane cap from the
electrode shaft.
Rinse the membrane cap and the electrode with a small amount of
electrolyte.
Place the lower edge of the nozzle of the electrolyte bottle vertically
downwards into the inside the membrane cap without touching the
membrane.
Fill the membrane cap in one movement up to the start of the thread with
electrolyte (see drawing), keep the nozzle in the electrolyte all the time. A
few very small bubbles may form.
Check that the membrane is fully wetted - the previously white membrane
will darken. If necessary, wait a while. Repeat filling if the membrane fails
to go dark.
Locate the electrode shaft vertically onto the filled membrane cap and turn
until the thread bites.
Turn the electrode shaft until the small hole below the rubber seal is visible
at the top.
Slowly tighten the membrane cap by hand (do not hold the rubber seal!).
The membrane must not be allowed to distort under the internal pressure
otherwise it will be unusable. Excess electrolyte should drain out of the
small hole below the seal as the sensor is screwed together.
Hands and sensor should be rinsed thoroughly in cold water in order to
remove excess electrolyte.
