accidental connection to the current
terminals. All models feature highenergy fuses and audible overload
alarms. A selectable auto power off
mode conserves batteries.

• True rms, dB/dBm available
Bench and field measurements
Agilent Technologies 970-series handheld multimeters give you much more
than just the basics. These compact
multimeters have the features you’d
expect from a bench meter, like
sophisticated math functions that
allow relative difference or percent
readings for checking tolerances and
Min/Max with time stamp to monitor
all types of measurements including
high resolution temperature readings.
These DMMs also include a hold feature to let you save readings manually
or automatically and a measurement
averaging capability to use when
you’re working with noisy signals. An
auto diode feature automatically
reverses polarity for you when you’re
checking semiconductor junctions.
The 971A is designed to withstand
the toughest environments. Like the
other handhelds in the 970 series, the
971A provides ac/dc volts, and current, ohms, continuity, diode test,
auto diode test, frequency volts and
°F and °C high-resolution temperature measurements.
Measure low-level dc/ac volts or
capacitance with the 972A
For measuring low-level signals, the
972A gives you 40 mV ranges for
dc/ac voltage and the assurance of 20
kHz frequency response. For capacitance testing, the 972A measures
from 10 pF to 1000 µF. A convenient
dual display shows the range, elapsed
time, or reference values, in addition
to your reading.
The 973A gives you more ways to
test and troubleshoot
The 31/2-digit display (with 0.1% basic
dc accuracy), 20 kHz frequency range,
true rms and ac+dc readings let you
measure sinusoidal and nonsinusoidal waveforms with confidence.
The 973A also gives you dBm and relative dB with dynamic range of 57 dB
(2 mV to 400 mV) or 74 dB (0.2 V to
1000 V), with 0.1 dB resolution. This
DMM also features dual displays.
Use the 974A when extra precision
is required
For precision measurements, the
974A gives you 41/2 digits with a
49,999 count full scale, and basic dc
accuracy of 0.05% for all ranges.
It also offers true rms, 100 kHz frequency response, dBm /relative dBm
readings, and ac+dc readings to accurately measure nonsinusoidal waveforms.
3-year warranty
With 970-series handheld multimeters
you get a manual, a high-quality test
lead set, a calibration certificate,
spare fuse, rubber boot, and two
installed AA batteries. Each instrument comes with a 3-year warranty.

Agilent E2373A Handheld Multimeter
Data Sheet
Low-cost multimeter with the
basic test capabilities you need
• dc and ac volts, dc and ac
current, resistance, audible
continuity, and diode test
• Auto or manual ranging
• Basic Vdc accuracy of 0.7%
• Maximum 1 kV dc, 750 V rms,
10 A
Basic handheld multimeter provides all-around testing
When low cost is crucial, the Agilent
Technologies E2373A handheld multi
meter is an ideal tool for troubleshooting and making portable
basic measurements. This versatile
multimeter measures dc and ac volts,
dc and ac current, resistance, and
provides diode test and audible continuity. With basic Vdc accuracy of 0.7
percent and a choice of auto or manual ranging, this low-cost meter is an
excellent choice for measurements in
the field or in the lab.
Easy to use
Display annunciators are included for
all functions as well as for low battery indication, overload conditions,
and range hold.
The 2373A features a large 31/2 digit
display (0.85 in./22 mm high LCD) as
well as a trend-indicating analog bar
graph that’s great for observing
peaks. Other features that make it
easy to use include a convenient tilt
stand and autoranging. The unit is
powered by two AA batteries which
typically last for 2,500 hours of use.
The E2373A multimeter is warranted
for a full three years. The unit comes
with test leads, batteries, a spare
fuse (0.5A/250V) and an operating
manual.

Every instrument and system we sell has
a global warranty. Support is available
for at least five years beyond the production life of the product. Two concepts
underlie Agilent’s overall support policy:
“Our Promise” and “Your Advantage.”
Our Promise
“Our Promise” means your Agilent test
and measurement equipment will meet its
advertised performance and functionality.
When you are choosing new equipment,
we will help you with product information, including realistic performance specifications and practical recommendations
from experienced test engineers. When
you use Agilent equipment, we can verify
that it works properly, help with product
operation, and provide basic measurement
assistance for the use of specified capabilities, at no extra cost upon request. Many
self-help tools are available.
Your Advantage
“Your Advantage” means that Agilent
offers a wide range of additional expert
test and measurement services, which you
can purchase according to your unique
technical and business needs. Solve problems efficiently and gain a competitive edge
by contracting with us for calibration, extracost upgrades, out-of-warranty repairs, and
on-site education and training, as well
as design, system integration, project management, and other professional services.
Experienced Agilent engineers and technicians worldwide can help you maximize
your productivity, optimize the return on
investment of your Agilent instruments and
systems, and obtain dependable measurement accuracy for the life of those products.
By internet, phone, or fax, get assistance
with all your test and measurement needs.
