Keysight U1231A 600V AC/DC True RMS Digital Multimeter with Data Logging

The Keysight U1231A is a feature-rich, 3½ digit handheld digital multimeter from the U1230 series, designed for professional electricians and technicians. Its ergonomic, contoured shape facilitates comfortable, single-handed operation, allowing you to illuminate the test area with the built-in LED flashlight while simultaneously selecting measurement functions via the anti-slip rotary dial. This multimeter provides True RMS measurements for accurate readings of AC voltage and current in real-world conditions, ensuring reliable diagnostics across a wide range of electrical work.

Key capabilities include measuring AC/DC voltage up to 600V, AC/DC current, resistance, frequency, capacitance, continuity, and diode testing. It offers both auto and manual ranging for user flexibility. The instrument excels in continuity testing, even in noisy environments, through a combination of an audible beeper and a flashing backlight display, providing clear visual and audio alerts. A valuable feature is its non-contact voltage (NCV) detection, allowing for the safe identification of live wires without direct contact.

For data management, the U1231A includes data logging functionality, capable of storing up to 10 readings. It also features IR-to-USB connectivity, enabling easy transfer of logged data to a PC for record-keeping and analysis. The low input impedance mode is designed to eliminate misleading 'ghost' voltage readings, enhancing measurement accuracy on installed wiring. Built for durability and safety, it boasts CAT III 600V overvoltage protection and an IP42 ingress protection rating against dust and water. With up to 500 hours of battery life from four 1.5V AA batteries and clear visibility from its backlit display or flashlight, this is a versatile and dependable tool for fieldwork.
