Keysight Technologies U1280 and U1240C series of Handheld Digital Multimeters

Keysight Technologies has launched two series of handheld digital multimeters (DMMs), the rugged U1280 and U1240C.

With 60,000-count display resolution and 0.025% accuracy, the U1280 series contains 4.5-digit handheld DMMs that offer precision, accuracy and repeatability needed to meet tough requirements for electronics manufacturing, installation and maintenance work in the electronics test industry. The U1240C series, by comparison, features 4-digit handheld DMMs which come with 10,000-count display resolution and 0.09% accuracy. These DMMs provide a broad range of measurement functions for installation and maintenance work in industrial facilities and also come with features such as ZLOW (which provides low impedance mode to eliminate stray voltages) and harmonic ratio (indicates the presence of harmonics).

An extended battery life (800 h for U1280 and 400 h for U1240C) allows users to test and log data over longer periods, while advanced functions and data logging capabilities are available for engineers through the Handheld Meter Logger software. This allows users to automatically log data in a trend plot or table format, manually log each measurement or convert the logged data into various test report formats.

Both series come with an IP67 certification for protection against dust and immersion of water up to 1 m, while the U1240C series is also CAT IV 600 V and CAT III 1000 V compliant to improve user safety in electrical testing and measurement.
