Keysight Technologies has announced two new ranges of handheld digital multimeters (DMMs). In addition to offering the capabilities and measurement functions needed for the electronics and industrial test segments, the U1280 Series and U1240C Series handheld DMMs are extremely rugged and come with extended battery life to allow users to test and log data over a longer period of time.

With 60,000-count display resolution and 0.025 percent accuracy, the U1280 Series is Keysight's highest performance handheld DMMs. These 4.5-digit handheld DMMs offer the precision, accuracy and repeatability engineers need to meet the toughest requirements for electronics manufacturing, installation and maintenance work in the electronics test industry.

The U1240C Series 4-digit handheld DMMs come with 10,000-count display resolution and 0.09 percent accuracy, and provide a broad range of measurement functions for installation and maintenance work in industrial facilities. The U1240C Series also comes with unique features such as low pass filter, ZLOW and harmonic ratio. The low pass filter function eliminates high frequency noise and harmonics, ensuring accurate measurement from a Variable Frequency Drive (VFD), and ZLOW provides low impedance mode to eliminate stray voltages. The harmonic ratio function gives an indication of the presence of harmonics.

"With extended battery life and IP67 certification, the U1280 Series and U1240C Series are designed to be reliable, durable and robust," said Ee Huei Sin, vice president, General-Purpose Electronic Measurement Division, Keysight. "With these new handheld DMMs, engineers can confidently perform tests and troubleshoot over a longer period of time even in tough electronics or industrial settings."

The U1280 Series and U1240C Series are robust and are suited to operation in the field. The handheld DMMs are certified to IP67 for complete protection against dust and immersion of water up to one meter, and are capable of withstanding up to a three-meter (ten feet) drop.

Additionally, the U1240C Series is CAT IV 600V and CAT III 1000V compliant to improve user safety in electrical testing and measurement. Both series of handheld DMMs come with extended battery life - 800 hours for the U1280 Series and 400 hours for the U1240C Series - so users can continue testing for longer periods of time. This is especially important for industrial test engineers whose ultimate goal is to keep the production line running seamlessly to prevent unplanned shutdowns.

For advanced functions and data logging capabilities, engineers can use the Handheld Meter Logger software, which allows users to automatically log data in a trend plot or table format, or to manually log each measurement with a touch of a button. Subsequently, users can convert the logged data into various test report formats. For remote monitoring, the U1280 Series and U1240C Series are compatible with the Keysight remote link solution, enabling safer and more convenient testing in hazardous environments, says the company.
