Do More with Just One Instrument
The basic model, U1251B, expands your capabilities beyond typical DMM measurements 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-resolu-
tion 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.
