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.
Measure with confidence
An innovative safety shutter prevents
accidental connection to the current
terminals. All models feature highenergy fuses and audible overload
alarms. A selectable auto power off
mode conserves batteries.
Use the rugged 971A in every
environment
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 4
1
/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.
