The U1280 Series 4-1/2 digit handheld digital multimeters excel in ruggedness and durability with IP 67 ratings, 10 feet drop-proof and up to 800 hours battery life. They optimize your productivity with the unique data logging and report generation functions designed to work seamlessly with Meter Logger software and optional remote switch probe.
Vsense for non-contact voltage detection (U1282A)
With the unique built in Vsense feature, you get a quick sense of AC voltage presence without the need to probe. When voltage presence is detected, it produces a unique combination of audible beeper alert and blinking LED light to alert you. This is especially useful to safeguard against exposure to live wires, suspected AC voltage presence, or simply an act of safety precaution before initiating a task. Work with peace of mind knowing your safety comes first with Keysight's U1280 Series handheld DMM.
Built-in low pass filter (U1282A)
Variable speed drives (VFD) are used to regulate the speed of three-phase AC motors to increase the efficiency of AC motors. However, the increased use of VFDs present challenges in getting accurate voltage, current and frequency measurements that match with readings shown on the VFD's control panel display. The U1281A and U1282A come with LPF (low pass filter) feature which blocks unwanted high frequency signal from VFDs' switching components. The net result is an accurate measurement of the output signal.
Manual logging made easy with Hold & Export button
Manual data logging conveniently records measurements and reduces error. Better yet, you're able to store measurement readings into the U1280 Series' internal memory and at the same time export the measurements to the Keysight Meter Logger software or Keysight Remote Link solution via the DMM's infrared port — all of these by simply pressing the Hold & Export button. When needed, the optional U5404A remote switch probe can be used to perform manual logging by emulating the Hold & Export button.
Keysight Meter Logger software provides a comprehensive data logging experience with the U1281A and U1282A, as well as other Keysight U1200 Series handheld DMMs. Your handheld DMM can be easily connected to the Meter Logger software that runs on a PC via Infrared (IR)-to-USB cable, or wirelessly — with the optional Keysight Remote Link solution. The data log measurements can be presented either by trend plot or table format for easy interpretation and further analysis — essential for troubleshooting and commissioning tasks. Once the measurements are recorded in the software, you can transfer the logged data into various types of report formats with just a click of the button.
The U1281A and U1282A comes with programmability capability that allows avid programmers to create computer programs to control the handheld DMM. The programmability of Keysight U1280 Series allows you to automate these DMMs, or even integrate them into larger test systems.
Includes: Test leads (red and black), Infrared (IR)-to-USB cable, Four (4) AA batteries, Quick Start Guide and Certificate of Calibration.
