6.3.6.1 Connection of pH or ORP sensors using a coaxial cable
NOTICE!
Possible incorrect measurement due to poor electrical contact
Only use this type of connection if you do not wish to use ready-made coaxial cables.
Note the following with this type of connection:
Remove the black plastic layer from the inner coaxial cable. This is present on all
types of cable. In doing so, ensure that individual threads of the shielding do not
come into contact with the inner conductor.
