Installing the miniLAB 1008

Universal Library for LabVIEW User's Guide

(installed with the Universal Library

for LabVIEW software)

Unpacking the miniLAB 1008

The miniLAB 1008 is shipped in an antistatic container to prevent damage by an
electrostatic discharge. To avoid such damage, perform the following procedure when
unpacking and handling your board:

1.

2.

3.

Before opening the antistatic container, ground yourself with a wrist-grounding
strap or by holding onto a grounded object (such as the computer chassis).

Touch the antistatic container to the computer chassis before removing the
miniLAB 1008 from the container.

Remove the miniLAB 1008 from the container.

If any components are missing or damaged, notify Measurement Computing Corporation
immediately by phone, fax, or e-mail:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.

Fax: 508-946-9500 to the attention of Tech Support

Email:

[email protected]

Be sure you are using the latest system software

Before you connect the miniLAB 1008 and install the software, make sure that you are
using the latest versions of the following software:

USB driver

Microsoft Data Access Components

.NET Framework
