The Agilent U1250 Series handheld digital
multimeters (DMMs) exceed your expectations by
delivering powerful features and performance
that meet your toughest requirements and
applications. The series’ latest multimeters,
the U1251B, U1252B and U1253B come in vivid
orange cases, offering capabilities and functions
equivalent to the U1250A Series.

Do more with just one
instrument
The basic model, U1251A/U1251B, expands
your capabilities beyond typical DMM
measurements to include data logging. The
U1252A/U1252B starts with the same
foundation, and then adds a 20-MHz frequency
counter and programmable square-wave
generator — so you’d be able to perform more
tests conveniently with one tool. What’s more:
both models come bundled with a complete set
of accessories to equip you right from the start
at no extra cost.
Offering the same functionality as the U1252A/
U1252B, the U1253A/U1253B is the world’s fi rst
OLED handheld DMM. You won’t have to squint
to be sure you’re reading it right: On the go or
on the bench, you’ll get crystal-clear viewing
indoors, even in dark, off-angle situations.

GUI data-logging software.
Find problems quickly
Troubleshooting can be tricky, especially when
you’re dealing with elusive problems. With the
U1250 Series’data logging capability, you can
ensure that every reading gets recorded
manually or at intervals you specify. Better yet:
you can have virtually unlimited data logging
saves when you connect any of the U1250
Series DMM to a PC with the optional IR-to-USB
cable.
In addition, the U1250 Series lets you achieve
greater confi dence in your measurements with
accurate true-RMS AC measurements, low DCV
error rate of up to 0.025% and high-resolution
display of 50,000 counts.
Uncompromising ruggedness and
safety
The U1250 Series DMMs are housed in robust
overmold enclosures, rated at CAT III 1000 V and
CAT IV 600 V and operate over a wide
temperature range of –20 °C to +55 °C. Each
DMM also include a 30 kA high energy fuse to
further protect you against violent fuse failures
during high-current measurements. Built tough
and certifi ed to stringent industrial standards,
the U1250 DMM is what you need to face the
demands of everyday tasks.
