How to Use this Manual
This manual describes how to set up and begin using your Quad
Tc/mV Amp. The use of the pH/mV Amp with the Chart software
Thermocouple Calibration extension is discussed. The appendices
provide technical and troubleshooting information.
Checking the Quad Tc/mV Amp
Before you begin working with the Quad Tc/mV Amp, please check
that:
• all items described in the packing list are included; and that
• there are no signs of damage that may have occurred during
transit.
Contact your eDAQ distributor if you encounter a problem.
You should also become familiar with the basic features of your
e-
corder
system, which are discussed in the
e-
corder
Manual
which will
be installed on you hard disk.
eDAQ Amps
The Quad Tc/mV Amp is part of a family of preamplifiers known as
eDAQ Amps.
The Quad
Tc/mV Amp is designed for recording signals from up to four
pH and other potentiometric electrodes. As with other eDAQ Amps, it is
designed to be operated under full software control and is
automatically recognized by Chart or Scope software which controls its
gain range, signal filtering, and other settings.
Chapter 1 —
Overview

The range of eDAQ Amps includes the:
•
Quad pH/mV Amp
, suitable for connection of pH, ion selective,
and potentiometric (ORP) electrodes
•
Potentiostat
, a three–electrode potentiostat that can be used for
voltammetric and amperometric experiments. Gain ranges of 20 nA
to 100 mA in 1:2:5 steps.
• Picostat, a high sensitivity three–electrode potentiostat suitable for
use with carbon fibre and other microelectrodes. Current gain
ranges of 10 pA to 100 nA in 1:2:5 steps.
• QuadStat, a four channel, three electrode potentiostat suitable for
use with amperometric biosensors. Current gain ranges of 2 nA
to1 mA/channel in 1:2:5 steps.
• Bridge Amp, suitable for sensors requiring a low drift, high gain
differential amplifier. Also provides DC excitation
• GP Amp, suitable for high output sensors requiring a high
impedance single ended or differential amplifier. Also provides DC
excitation.

CHAPTER TWO
2The Quad Tc/mV Amp
This chapter describes how to connect and use your eDAQ Quad
Tc/mV Amp.
IMPORTANT: Always make sure that the e-corder is turned off before
you connect or disconnect the Quad Tc/mV Amp. Failure to do this
may result in damage to the e-corder and/or the Quad Tc/mV Amp.

The Front Panel
The front panel of the Quad Tc/mV Amp is shown in Figure 2–1.
The Thermocouple Inputs
The miniature thermocouple input connectors marked ‘Cu’ and ‘+’ of the
Quad Tc/mV Amp provide connection for most types of thermocouple.
The On-line Indicators
When lit, these indicate that the Chart software has located and
initialized the Quad Tc/mV Amp. If the light does not go on when the
software is run, check that the Quad Tc/mV Amp is properly
connected.
