Vsense for non-contact voltage detection

Troubleshooting in most electrical environment 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 a peace of mind knowing your safety comes first with Keysight’s U1280 Series handheld DMM.

Comprehensive data logging experience with Keysight Meter Logger software

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. Keysight Meter Logger software provides users the flexibility and useful configuration to log their measurements, such as the flexibility to select sample interval, enable limit levels on the data log and email notification option 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 the button.

Manual logging made easy with Hold & Export button

While data logging over a period of time is useful to capture measurements for further observations and analysis, manual data log is just as useful to conveniently record measurements and reduce human error occurrence from conventional manual data entering 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 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.
