The Keysight U1282A is a rugged, 4.5-digit handheld digital multimeter engineered for demanding industrial environments. It offers a high-resolution 60,000-count dual display and boasts a basic DC voltage accuracy of 0.025%. This device is built to withstand harsh conditions, featuring an IP67 rating for water and dust protection and drop-tested to withstand a 10-foot (3-meter) impact. The U1282A provides extensive measurement capabilities, including voltage, current, frequency, capacitance, resistance, continuity, diode testing, and temperature. Additional features enhance its utility for troubleshooting and maintenance, such as a built-in low-pass filter for variable frequency drive (VFD) analysis, a non-contact voltage detection (Vsense) feature with visual and audible alerts, a frequency counter, and a square wave output. With up to 800 hours of battery life, this multimeter ensures prolonged operational uptime.
