Data Sheet
Introduction
Retool your expectations with the new Keysight Technologies, Inc. U1230 Series Handheld
DMMs — the first to combine a built-in LED flashlight, both audible and visual alerts, and
non-contact AC voltage detection in one handheld.
Whether it is dark, noisy or even dangerous, the U1230 Series handheld digital multimeters
keep you equipped with features that anticipate worst-case scenarios. The ergonomic
shaped handheld allows you to single-handedly illuminate the test area with a built-in
flashlight while selecting measurement functions using the rotary dial. Vsense performs
non-contact voltage detection while continuity detection is made easy with the audible
beeper alert and flashing backlight display. With the U1230 Series, you work better in the
conditions you are in.

Features
–– Built-in LED flashlight to illuminate test area
–– Flashing backlight as additional visual alert during
continuity tests in noisy environments
–– Vsense to perform non-contact voltage detection
–– Data logging capability (stores up to 10 readings)
–– IR-to-USB connectivity to transfer data to PC for record
Ergonomically shaped with a built-in flashlight
Built for handheld users working in a poorly lit environment, the U1230 Series allows you
to single-handedly illuminate your test area while making measurements with its easily
activated built-in flashlight. Its ergonomic shape fits your hand, while the easily accessible
rotary dial allows selection of measurement functions.
Flashing backlight and beeping alert for continuity detection
The U1230 Series is built for continuity detection in dark and noisy environments. Its audible
beep and flashing backlight display provides increased visual and audio alert to indicate
continuity.
Non-contact voltage detection with Vsense
The Vsense, a unique feature found in the U1233A model performs non-contact voltage
detection. It delivers more safety while making measurements in dangerous working
environments by avoiding any contact with hot or live wires. Upon detection of voltage,
it produces a unique combination of beeping alert and blinking LED light to make
measurements more efficiently – especially in a dark or noisy environment.

environment, 120 minutes of operating time is required instead.
3. The accuracy does not include the tolerance of the thermocouple probe.

6. The approximate ambient temperature (cold-junction compensation) is shown on the display when you have an open thermocouple.The
open thermocouple message may be due to broken (open) probe or because no probe is installed into the input jacks of the multimeter.
7. For temperature measurement on U1233A, the type-K thermocouple probe and adapter such as the U1186A (purchase separately) is
required.
8. For auxillary temperature measurement on U1231A & U1232A, a temperature module such as the U1586B (purchase separately) is required.
