Keysight U1190 Series Clamp Meters Data Sheet Introduction Keysight Technologies, Inc., U1190 Series clamp meters are packed with a wealth of features to help you work more conveniently and more safely. Designed in a robust case--the unique wire separator makes it easy to measure individual wires in a bundle. The built-in LED lashlight illuminates your test area while Vsense performs non-contact voltage detection. What's more, the U1190 Series clamp meters are CAT III 600 V and CAT IV 300 V certiied. Use Keysight U1190 Series clamp meters and retool your expectations in handheld tools. Features The U1190 Series clamp meters include: - Unique wire separator to separate wires from a bundle - Vsense to perform noncontact voltage detection1 - Built-in LED flashlight to illuminate test area1 - Visual (backlight alert) and audible continuity indication in noisy environments Unique wire separator with a built-in lashlight Vsense for non-contact voltage detection 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 measurements 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. 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 working environments. Upon the detection of voltage, a unique safety alert of an audible beeper is produced to alert users.
