pH Amp Owner’s Guide

How to Use This Guide
This owner’s guide describes how to set up and begin using your
pH Amp. The chapters give an overview of front-ends in general and
the pH Amp in particular, and discuss how to connect the hardware,
perform a simple power-up test, and use the front-end with some
ADInstruments programs. The appendices provide technical
information and solutions to possible problems, and there is an index.
Checking the pH Amp
Before connecting the pH Amp to anything, check it carefully for signs
of physical damage.
1. Check there are no signs of damage to the outside of the front-end.
2. Check there is no obvious sign of internal damage, like rattling.
If you have found a problem, contact your authorized ADInstruments
representative immediately, and describe the problem. Arrangements
can be made to replace or repair the front-end.
ADInstruments Front-ends
The PowerLab system consists of a recording unit and application
programs on the computer to which the unit is connected. It is an
integrated system of hardware and software designed to record,
display, and analyze experimental data. Your pH Amp is one of a
family of front-ends meant for use with your PowerLab system.
Front-ends are ancillary devices that extend the system’s capabilities.
They provide additional signal conditioning and other features, and
extend the types of experiments that you can conduct and the data
you can record. All ADInstruments front-ends are designed to be
operated under full software control. No knobs, dials or switches are
needed, although some may be provided for convenience or safety.
Connected front-ends receive power and control signals from the
PowerLab through the I
2
C (eye-squared-sea) bus. Each new front-end
added to the system connects to the previous front-end, in a simple
daisy-chain structure. This makes it very easy to add front-ends to the
system or to transfer them between PowerLabs.
