U1250 Series

The U1250 Series is a 4½-digit DMM with a high-resolution display of 50,000

counts. The U1250 Series lets you achieve greater confidence in your measure-

ments with accurate true RMS AC measurements and a low DC voltage rate

up to 0.025%. Agilent U1251A/B and U1252A/B handheld DMMs expand

your capabilities beyond typical DMM measurements to include data logging.

The U1252A/B starts with the same foundation as the U1251A/B and adds a

20-MHz frequency counter and programmable square-wave generator, so you

can conveniently perform more tests with one tool.

Offering the same functionality as the U1252A/B, the U1253A/B is the world’s

first organic light emitting diode (OLED) handheld DMM. It is designed with

high a contrast ratio of 2000:1 and a wide viewing angle of 160°. You can

toggle the large numerical display to dual-display mode, with both displays at

50,000-count high resolution. As a result, you get crystal-clear viewing outdoors

and indoors—even in dark, off-angle situations.

U1270 Series

The U1270 Series is a 4½-digit DMM with 30,000 counts resolution. This series

comes with flashing backlight alert with audible continuity indicator, and dust

and water resistance. This series is designed for maximum efficiency and

productivity in industrial settings. The U1270 Series offers convenient functions

such as Z

LOW

to eliminate stray voltages, Smart Ω to minimize false readings

due to leakage current, and Qik-V to determine the existence of AC and/or DC

voltages. When it comes to VFD troubleshooting, the U1270 Series has LPF to

handle the job with ease. The U1270 Series is IP 54-certified to protect against

water, dust, and damage. The loud beeper and backlight alert function, which

flashes the backlight to indicate continuity, facilitates continuity detection in

noisy and dark environments.

Agilent also provides various types of standard test lead kits and accessories

for high current and temperature measurement. IR-to-USB cables make it easy

to connect the DMM to a PC. Every unit is shipped with test probes using 4-mm

tips, a length that reduces the likelihood of high-energy sparking, especially in

CAT IV environments.

Agilent U1240, U1250, U1230, and U1270 Series use 30-kA fuses to provide

greater protection from high-voltage transients. Most comparable DMMs use

10-kA fuses. During qualification of the 30-kA fuse, all models pass HIPOT test-

ing at 2,000 VAC and 2,000 VDC between the microamp, milliamp, and ampere

terminals, and common ground.

The U1240, U1250, and U1270 Series DMMs are housed in robust over-mold

enclosures, rated at CAT III 1000 V and CAT IV 600 V, and suited for use over a

–20 to +55 °C temperature range. The U1230 is rated at CAT III 600 V and suited

for use over a –10 to +55 °C temperature range.
