13.4 Cleaning the working electrode

#
Warning!
The electrolyte solution irritates the skin and eyes. For this reason:
• Always wear suitable protective gloves and goggles/face mask.
• Wash skin which has come into contact with the electrolyte solution thoroughly with plenty
of water and change wetted clothes immediately.
• If electrolyte gets into your eye, rinse thoroughly with plenty of water and consult a doctor.
• Observe the instructions on the safety data sheet.
!
Note!
The working electrode only has to be cleaned in the event of underslopes or overslopes (= sensor
cannot be calibrated) which cannot be rectified by replacing the electrolyte or the membrane
cap.
Unscrew the basket protector and
membrane cap.
"
Caution!
To protect the working electrode against damage:
Do not use conventional abrasive paper or a fiberglass brush.
Then fit a new membrane cap with a fresh filling of electrolyte (--> "Replacing the electrolyte
and membrane cap").
