Product Overview
The Fluke 2638A HYDRA Series III Data Acquisition Unit (the Product or Instrument) is
a portable bench-top data logger that measures and records dc volts, ac volts, dc current,
ac current, resistance, frequency, and temperature (see Table 1-1). See the Specifications
section for information on the types and ranges of the measurement inputs the Product
can accept.
Features of the Product include:
•
Scan – Sequentially scan up to 67 analog channels per scan sweep. In addition, the
Product also has 20 math channels, one DIO channel, and one TOT channel that can
be included in scan. A scan can be manually controlled from the front panel or
triggered with a variety of triggers such a timer, an alarm, an external source, or a
remote SCPI command.
While a scan is in progress, all channel values can be viewed on the display in a
spreadsheet format along with statistics such as average, standard deviation,
minimum, maximum, peak-to-peak, and rate-of-change. With the Graph feature,
channel measurement data for up to four channels can be plotted and viewed on the
display. Users can toggle the data mode with a softkey to view live data or historical
data.
•
Monitor – View the measurement value or the statistics of a single channel. Monitor
is an independent feature that can be used while a scan is in progress or inactive.
Much like the Scan feature, the statistics of the single measurement can be viewed on
the display or be shown in a graph.
•
Data Storage - Store up to 20 Mb of data and channel setup files directly to the
internal non-volatile memory or an external USB drive. Data can also be transferred
to a PC with a USB drive or LAN TCP/IP interface at the rear of the unit with SCPI
interface command sets.
