In general, each front-end connects to an input channel of the
PowerLab, although the Stimulus Isolator and similar front-ends
connect to the positive analog output of the PowerLab.
Front-ends are automatically recognized by the PowerLab system.
Any front-end feature such as gain or filtering is combined with the
appropriate features of the program and presented as a single set of
software controls. This seamless integration of front-ends greatly
increases the flexibility and ease of use of the PowerLab system.
The pH Amp
The pH Amp is designed for recording signals from pH and other
potentiometric electrodes, and it operate under full software control.
It is automatically recognized by ADInstruments software, which
controls the gain range, signal filtering, and other settings.

The Electrode and Reference Input
The BNC input connector of the pH Amp provides connection for a
pH, ISE or redox electrode. Combination electrodes, that is those with
an internal reference, will only need to be connected to this input.
Electrodes that do not have an internal reference (most ISEs and some
pH electrodes), will need to be used with a separate reference
electrode. This electrode is connected via the 4 mm Reference socket
and shares the shield (ground) of the BNC electrode input connector.
