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.
Programmable
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.
N2751A InfiniiMode differential probes are a new generation of low-cost differential active probes compatible with Keysight InfiniiVision and Infiniium oscilloscopes’ AutoProbe interface.
Quick Action Scope Control
The N2751A differential probes provide quick and convenient access to various functions on the scope. You often need to control the scope while you hold a probe in your hand. With the quick action scope control feature built into the probe, you can turn the built-in headlight of the probe on and off, or control some frequently used scope functions such as RUN/STOP, auto scale, quick print, quick save, etc. with only a button press on the probe. Get control of your most needed function with a push of the quick action control button on the probe. The following scope functions can be controlled with the quick action control button.
Measurement Versatility
These probes integrate many of the features and characteristics needed for today’s general-purpose, high-speed differential probing — especially in digital system design, component design/characterization, and differential serial bus measurements. The N2750A Series differential probes offer 2:1 and 10:1 dual attenuation settings, allowing them to be used for a broad range of applications. Dual attenuation range is automatically configured depending on the size of the input signal. These differential probes have an input resistance of 200 kΩ (differential) or 100 kΩ (each input to ground) and an extremely low input capacitance of 700 fF to minimize circuit loading. This, accompanied with superior signal fidelity, makes these probes useful for most digital design and debug applications. And with their wide dynamic range (10 Vpp at 10:1) and offset range (±15 V), these probes can be used in a wide variety of analog signal measurements as well.
InfiniiMode
The N2751A InfiniiMode probe comes with new InfiniiMode operation modes. The InfiniiMode allows convenient measurements of differential, single-ended, and common mode signals with a single probe tip, without reconnecting the probe to change the connection. The N2751A probe’s InfiniiMode provides the following modes of operation.
