Handle big currents –
more safely
Keysight U1210 Series
Handheld Clamp Meters
Introduction
Measurements of electrical distribution cables can be challenging and risky. For cables up to two
inches in diameter, the Keysight Technologies, Inc. U1210 Series handheld clamp meters enable high-
current measurements without breaking the circuit. Unlike most clamp meters, they also include DMM
capabilities—resistance, capacitance, frequency and temperature—to simplify troubleshooting during
installation and maintenance. Best of all, they provide an extra layer of protection with CAT IV 600V
and CAT III 1000 V safety ratings.
Features
– Large clamp opening of 52 mm or 2”
– High measurement capability of up to 1000 A for AC, DC or AC+DC
– CAT III 1000 V/CAT IV 600 V safety rating
– Bluetooth® wireless connectivity (optional U1177A Infrared (IR)-to-Bluetooth Adapter required)
– Includes full-featured DMM with resistance, capacitance, frequency and temperature functions
– High resolution measurements – measure current as low as 0.01 mA
– Peak hold
– Dual ranging mode – manual and auto
– Large dual display
– Min/max recording capability

Key Measurements
Measure current easily
and accurately
Keysight U1210 Series handheld
clamp meters come with clamp
opening of 52 mm/2 inches and high
current measurement capability of
up to 1000 A (AC, DC, AC+ DC). With
the large jaw size, these handhelds
simplify current measurements for
thick cables. Clamp on with the
U1210 Series and get convenience,
versatility and the ability to handle big
currents—safely.
Smooth sailing
measurements even in a
distance
Making current measurements can
be strenuously demanding due to its
complexity and high current involved.
Electrical distribution rooms being
typically situated at different areas
further complicates maintenance
and troubleshooting due to the need
to commute back and forth to cross
check measurement results.
By adding the new Bluetooth
capability to your existing U1210
series handheld clamp meters,
you are able to make high current
measurements in a safer and more
Full-featured digital
multimeter functions
The U1210 Series handheld clamp
meters provide basic functions of a
multimeter with wide measurement
ranges to cater for a broad range of
applications (ACA, DCV, ACV, OHM,
audible continuity, diode and frequency
tests). These meters also provide
auto-ranging capability, built-in peak
hold for in-rush current measurement,
temperature and capacitance mea-
surement capability, large backlight
display and one-hand operation.
convenient manner. With the U1177A
Infrared-to-Bluetooth adapter, you
can easily monitor measurements and
log data up 10-metres range across
all Android platform devices—
an added value for maximum
efficiency and productivity in
all sorts of hard-to-reach
environments.

Ensure that the clamp meter measures only one conductor at a time. Measuring
multiple conductors may cause inaccuracy in measurement reading due to vec-
