TRADE NEWS: Agilent Technologies Introduces Next-Generation 6½ Digit Digital
Truevolt Technology Helps Engineers Continue to Measure with Confidence
SANTA CLARA, Calif. -- June 17, 2013
Agilent Technologies Inc. (NYSE:A) today introduced the Truevolt Series
digital multimeters. These DMMs offer several advantages over previous models.
They help engineers see their measurement data in new ways, get actionable
information faster, and document their results more easily. Exclusive Truevolt
technology reduces extraneous factors such as noise, injected current and
input bias current for increased measurement confidence.
The Agilent 34461A DMM is a direct replacement for the industry-standard
Agilent 34401A DMM, and was designed to make migration easy for current users
of the 34401A. The Agilent 34460A offers engineers a basic entry point to the
6½ digit class of DMMs.
Compared with the 34401A DMM, the new 34461A offers expanded current ranges
from 100 µA to 10 A. Both the 34460A and 34461A have a temperature measurement
function (RTD/PT100, thermistor) and expanded diode measurement capability to
allow engineers to measure a larger full-scale voltage (5 V) so they can test
more diode types, such as LEDs.
“Our customers rely on their 34401A DMMs and trust the answers they get,” said
Gary Whitman, vice president and general manager of Agilent’s System Products
Division. “Now they can easily migrate to the Truevolt Series DMMs and have
even more confidence in their results, along with greater ease of use and new
capabilities. Thanks to innovative Truevolt technology, we are continuing to
offer our customers a good balance of measurement resolution, linearity,
accuracy and speed at a value price.”
Most DMMs show results on a low-resolution numeric display. With the Agilent
Truevolt Series, engineers get a 4.3-inch, high-resolution, color display to
view numerical readings, long-term trends (34461A only), measurement
histograms and statistical information. They can also set display preferences
and pull them up automatically the next time they start up the instrument.
Driverless easy file access USB file transfer provides simple USB connectivity
between an Agilent Truevolt DMM and a PC, using the standard USB media
transfer protocol. Engineers can drag and drop measurement data, instrument
settings and screen images into PC applications without any additional
The Digital Multimeter Connectivity Utility software lets engineers control,
capture and view the Agilent DMMs on their benches. With a single click they
can transfer data to a PC via USB, GPIB, LAN or RS-232 (when used with
older-generation Agilent DMMs).
Real-world signals are never flat. They have some level of AC signal riding on
top from power line noise, other environmental noise, or injected current from
the meter itself. How well a DMM deals with extraneous factors and eliminates
them from the true measurement makes a big difference to its accuracy. Using
patented analog-to-digital converter technology, Agilent Truevolt Series DMMs
account for measurement errors created by these real-world factors, so
engineers can be confident in their measurements.
*Agilent Truevolt DMMs have less than 30 percent of the amount of injected
current attributed to the meter compared with DMMs made by other vendors.
*In real measurement situations, input currents create measurement errors,
adding voltages to DMM results. Truevolt DMMs take care of input bias
current. Other vendors’ DMMs offer 20 percent to infinitely poorer
performance (some are too noisy to get any measured results).
*In the 6½ digit class of meters, only Agilent uses digital direct sampling
techniques to make AC rms measurements. This results in a true rms
calculation and avoids the slow response of analog rms converters used in
all other vendor’s 6½ digit DMMs, allowing for crest factors up to 10
without additional error terms.
