The last thing you want is for your tools to run out of juice when you need it the most. The U1280 series handheld DMMs let you carry out tests and measurements over a longer duration than ever before. With up to 800 hours of battery life, you have a handheld DMM that works for a long time minus the hassle of battery change, especially useful for frequent usage or prolonged testing. Put your battery concerns behind and fully focus on your work at hand, as it should be for maximum productivity. When operating in harsh conditions, you’d need tools that are strong enough to stand up to the task. The U1280 series are housed in robust over-mold enclosures and certified to IP 67, providing superior protection to monitor against dust and water immersion. Better yet, it is also designed to absorb the impact of a 3-meter (10 ft) drop.

Gain the confidence to achieve trustworthy measurements thanks to the precision, accuracy and repeatability of the Keysight U1280 series handheld digital multimeters (DMMs). Get accurate and reliable measurement with 60,000-count display resolution and 0.025% basic DCV accuracy for troubleshooting electronic circuits of the system.

Vsense for NCV Detection (U1282A Model)

Troubleshooting in most electrical environments is typically dangerous due to the high voltages involved. Now 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 users. This is especially useful to safeguard users from 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.

Comprehensive Data Logging

When it comes to the need to observe measurements over a period of time, Keysight Meter Logger software provides a comprehensive data logging experience with Keysight U1280 Series as well as other Keysight U1200 Series handheld DMMs. The handheld DMM can be easily connected to the Meter Logger software that runs on a PC via Infrared (IR)-to-USB cable, or do so wirelessly with the optional Keysight Remote Link solution. Keysight Meter Logger software provides users the flexibility and useful configuration to log their measurements, such as the flexibility to select sample intervals, enable limit levels on the data log and email notification options for when the limit is exceeded. 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, users can transfer the logged data into various types of report formats with just a click of a button.

While data logging over a period of time is useful to capture measurements for further observations and analysis, a manual data log is just as useful to conveniently record measurements and reduce human error occurrence from the conventional manual data entering the process. Better yet, users are able to store measurement readings into the handheld DMM’s 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 the situation requires users to concentrate on probing, the optional U5404A remote switch probe can be used to perform manual logging by emulating the ‘Hold & Export’ button of the U1280 Series handheld DMMs.

Built-in Low Pass Filter (U1282A Model)

Today, three-phase AC electric motors are the most important workhorses in industry and commercial facilities. With the advent of solid-state electronics, 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 presents challenges to technicians in getting accurate voltage, current and frequency measurements that match with readings shown on the VFD’s control panel display. Many true RMS DMMs that have high AC bandwidth are measuring VFD signals up to 20% to 30% higher than the drive’s controller display due to the reason that DMMs are measuring the carrier frequency/switching frequency generated by VFDs. Keysight U1280 Series comes with LPF (low pass filter) feature which blocks the unwanted high-frequency signals from VFDs’ switching components. The net result is an accurate measurement of the VFD’s output signal which helps to expedite the maintenance or troubleshooting tasks of VFDs.

Programmable

Keysight U1280 Series comes with programmability capability that allows avid programmers to create computer programs to control the handheld DMM. The programmability of the Keysight U1280 Series allows users to automate Keysight U1280 Series or even integrate it into bigger test systems.
