Do More with Just One Instrument
The basic model, U1251B, expands your capabilities beyond typical DMM measure-
ments to include data logging. The 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 U1252B, the U1253B is the world’s first 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.

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 confidence 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 certified to stringent industrial standards, the U1250 DMM is what you
need to face the demands of everyday tasks.
