Unique wire separator with
The U1190 Series clamp meters are built to
perform in the environments you work.
The unique wire separator allows you to
effortlessly isolate and perform measure-
ments on individual wires in a bundle.
For improved visibility when making
measurements, these clamp meters also
come with an easily activated built-in LED
flashlight that illuminates the test area.
These features ensure that you are better
equipped when making measurements.
Vsense for non-contact
voltage detection
The U1190 Series clamp meters have
Vsense—a unique method of non-contact
voltage detection that safeguards users
from exposure to hot or live wires while
making measurements in dangerous work-
ing environments. Upon the detection of
voltage, a unique safety alert of an audible
beeper is produced to alert users.
Ergonomically built with
current measurement
up to 600 A
Ergonomically built, the U1190 Series
clamp meters fit comfortably in the palm
of your hand and allow you to select
measurement functions with just a simple
thumb press. Better yet, the U1193A and
U1194A come with a current measurement
up to 600 A. The wide range of current
measurement functions cover an array of
applications such as electrical installation,
maintenance, and troubleshooting tasks—
making it an ideal tool to use across many
industrial applications.

Accuracy is given as ± (% of reading + counts of least significant digit) at 23 °C ± 5 °C, with relative humidity less than 80% RH. AC voltage
and AC current specifications for U1193A and U1194A are AC coupled, true rms and are valid from 5% of range to 100% of range. The crest
factor may be up to 3.0 at 4,000 counts. For non-sinusoidal waveforms, add additional accuracy of (2% reading + 2% full scale) typically. In
the EMC RF field of 3 V/m, total accuracy is specified as specified accuracy + 30 digits for all functions.
