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:

Plug the electrode plug into the Ind. socket of the 867 pH Module.

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:

Plug the electrode plug into the Ref. socket of the 867 pH Module.
