1. Safety instructions
To guarantee the safe functioning of the
3B NET
log
™ equipment, it is necessary to
abide by the following instructions:
•
Do not connect the 3B NET
log
™ device to
a voltage in excess of ±20V or current in
excess of ±2A.
•
Make sure the 3B NET
log
™ device does
not come into contact with water.
•
The 3B NET
log
™ device should not be
exposed to temperatures above 80°C.
The operating voltage input is protected
against polarity reversal. However, it is not
protected against excess voltage.
•
Do not apply voltage in excess of 4.5V to
the operating voltage input.
Use of the Ethernet port requires a power sup-
ply of higher power rating.
•
When using the 3B NET
log
™ unit with the
Ethernet port, supply power by means of a
plug-in power supply.

3. Introduction
3B NET
log
™ is a multimedia data acquisition
and evaluation system for current and voltage
measurements and for measurements using
sensors. The system can be used with or with-
out being connected to a computer. With the
accompanying 3B NET
lab
™ software, meas-
urements can be conducted with arbitrarily
chosen parameters as well as in prepared
experiments. The prepared experiments take
the user through an interactive experimental
environment where the measurement parame-
ters have already been defined. When used-
within a network, the teacher and students can
mutually monitor their results.
The Ethernet port allows the 3B NET
log
™ unit
to be directly connected to a local network, so
that data can be sent to any computer in the
network for evaluation. In order to use the unit
with Ethernet an intranet in the same sub-
network must be in place.
Without being connected to a computer, the
3B NET
log
™ device can be used as a digital
multimeter for current and voltage measure-
ments. Combined with different sensors, the
3B NET
log
™ equipment can also be used as a
handheld unit with automatic sensor recogni-
tion.

The computer reports that it has detected a
new hardware.
Windows XP:
•
Do not activate Windows Update.
•
Select “Install software from specified loca-
tion”.
•
Under “Browse”, specify the location of the
driver on the CD.
•
A hardware message will state that the
software has failed to pass the Windows
