867 pH Module
3.5 Connecting sensors
The measuring interface contains the following measuring inputs:
￭ Ind. for a potentiometric electrode (pH, metal or ion-selective elec-
trode)
￭ Ref. for a separate reference electrode
￭ Temp. for a temperature sensor (Pt1000 or NTC)
￭ Pol. for a polarizable electrode
￭ iConnect for an iConnect (measuring interface for electrodes with
integrated data chip, so-called iTrodes)
3.5.1 Connecting a pH, metal or ion-selective electrode
Connect the pH, metal or ion-selective electrode as follows:
1 Plug the electrode plug into the Ind. socket of the 867 pH Module.
Figure 12 Connecting a pH, metal or ion-selective electrode
NOTE
The electrode cable is protected against accidental disconnection
of the cable by means of a pull-out protection. If you wish to pull
out the plug again, you will first need to pull back the outer plug
sleeve.
3.5.2 Connecting a reference electrode
Connect the reference electrode as follows:
1 Plug the electrode plug into the Ref. socket of the 867 pH Module.
