Data Sheet

Features

Simply right for your basic needs,

without compromising quality

The U3400 Series digital multimeters

(DMMs) come with functions vital for your

everyday measurements: DC, AC and AC+

DC voltage and current, 2- and 4-wire

resistance, frequency, continuity and

diode tests.

Math functions dBm, Min/Max, Relative,

Compare, Hold and Percentage** are also

available to ease your measurement

analysis.

Not only are the U3400 Series built robust

for lasting reliability over the long haul,

these DMMs also ensure dependable

measurements with up to 0.012% basic

DCV accuracy.

Efﬁcient testing with dual display

and selectable resolutions*

Dual display on the U3400 Series lets you

view two parameters simultaneously as you

Physical security

Your instruments may be at risk of theft or

misplacement whenever you leave them

unattended on the bench. With the U3400

Series’ rear Kensington lock slot, you can

secure your DMM and be assured that it is

where you expect it to be for your continued

testing the next day.

measure, and further enhances your

troubleshooting tasks. For example, the

ability to see both AC voltage and

frequency simultaneously would help you

to measure the frequency response of

ampliﬁer circuits more efﬁciently and

effectively. Refer to Page 3 for more typical

dual display combinations and applications.

Up to three measurement speeds are

available on the U3402A: Slow, Medium and

Fast. This means greater ﬂexibility in

catering to different testing needs: a faster

measurement speed at lower resolution or

a higher resolution at slower measurement

speed.

Up to 120,000 counts resolution

Up to 0.012% basic DCV accuracy

11 basic measurements and up to

six built-in math functions

Dual display on bright VFD

Selectable resolutions for variable

measurement speeds*
