Quick-start Guide for System Installation

Your shipment includes a short document entitled Quick-start Installation Guide–USB Potentiostat. It contains
the latest instructions for installing Gamry hardware and software onto a computer system. If this document is
missing, the following information should be sufficient for you to install the Gamry Framework Software and
Gamry potentiostat onto your computer.

Software Installation

The Reference 3000 is compatible with the Windows

®

Plug & Play configuration system. Like most Plug & Play

hardware, it is best if you install the software for the Reference 3000

before

you install the potentiostat

hardware.

Gamry Software Setup program normally starts automatically when you place the Gamry Instruments Software
disk (or Gamry Instrument Software flash drive) into your computer.

If you have inserted the Gamry CD or Flash Drive into your computer and the Gamry Setup program does not
start automatically:

1)

Navigate to the root folder of the device containing the Gamry Software (CD or flash drive) or to a
Windows

®

folder containing the Gamry Software.

2)

Run the program called

Autorun.exe

found in this folder.

If you do not know how to navigate to the Gamry Installation device, consult your local computer expert or
network administrator or email

[email protected]

.

Reboot your Computer after Software Installation

Reboot your computer after the Gamry Setup program is done. The Setup program normally offers you the
opportunity to do so. USB device drivers are usually loaded when Windows boots up. Following Setup, you
may not be able to use your Reference 3000 until the drivers are loaded.

Device-driver installation may not occur until a while after the Windows

®

Desktop appears.

On a slow computer, or a busy computer with lots of active applications, the delay before driver installation
can be a minute or more.
