5 Fluke Corporation Fluke 2638A Hydra Series III Data Acquisition System/Digital Multimeter
Memory management
The main panel memory key opens
a simple menu for managing data
files and setup files. If you want
to load a previously saved setup
file for a test, simply select your
file from either internal memory
or from a USB drive and you are
ready to start scanning. You can
easily move stored internal data
to a USB for PC analysis or move
setup files to another 2638A. With
Hydra Series III you have easy
access to data without the need for
a direct PC connection.
To help safeguard your test
data in the case of a power
outage, the 2638A has a menu
selection to resume scanning in
the same configuration immedi-
ately when power is restored. It is
just another way the 2638A works
with and protects your data.
Flexible triggers and
resolution
To begin a scan, you have several
options that can be set in your test
setup menu:
• External trigger
• Remote SCPI command
• Alarm trigger
• Time interval trigger
• Manual trigger initiated from
the front panel
Measurement resolution is at your
control with the 2638A. You can
choose between standard set-
tings of Fast, Medium or Slow (4.5,
5.5, 6.5 digits) for the resolution
you need. You can also select
custom measurement speeds on
individual channels to get the
accuracy and resolution to suit
your requirements.
Totalizer
A totalizer input located on the
rear panel provides a simple coun-
ter that records to the data file on
every scan. The totalizer count can
accumulate up to 1,048,575 counts
and be reset from the front panel
or remote command.
Channel statistics
Each channel’s measurement
statistics can be viewed at any
time. During scanning, monitor-
ing or in DMM mode, you have
rate-of-change (per minute and
per second), standard deviation,
minimum, maximum, peak-to-
peak, and average—all available at
the touch of a button.
Connectivity
USB (virtual serial port) and LAN
interface connections are avail-
able for easy connection to your
company network or direct to you
PC. Use Fluke DAQ application
software for the 2638A or develop
your own interface with the stan-
dard SCPI command set, or use our
Lab View driver or Indusoft Web
Studio to support your specific
application needs.
Category II international
safety ratings
The Hydra Series III is the only
general purpose portable data
acquisition system with an IEC
Category II safety rating to help
protect you and your operators
when making real-world measure-
ments on machinery in industrial
areas. Other data loggers that are
not clearly rated for these types
of category measurements should
be reviewed before being used
for industrial measurement. Fluke
takes your safety and your mea-
surements seriously.
A note on measurement safety
An instrument’s safety ratings should always
be reviewed before performing any electrical
measurement. Data loggers should not be an
exception to that rule.
It is sometimes mistakenly assumed that a
high voltage input specification on a data logger
makes it safe to use on or near industrial equip-
ment or to monitor mains power. This is not
always the case. The Fluke Hydra Series III was
designed specifically to meet stringent CAT II
safety standards.
