7.3.6.1 Connection of pH or ORP sensors via a coaxial cable
NOTICE!
Possible incorrect measurement due to poor electrical contact
Only use this type of connector if you do not wish to use pre-assembled coaxial cables.
Observe the following for this type of connection:
Remove the black plastic layer from the inner coaxial cable. There is a black plastic layer on
all types of cable. In doing so, ensure that individual threads of the shielding do not come
into contact with the inner conductor.
