The Keysight (Agilent) 971A is a rugged, handheld 3.5-digit digital multimeter delivering essential electrical measurements for field technicians, students, and hobbyists. Built with a tough package and rubber seals, it withstands demanding environments while offering dual digital display capability for simultaneous readings or auxiliary data such as elapsed time.
Technical Specifications
The 971A provides measurement across nine core functions. DC voltage measurement reaches 1.0 kV with ±0.3% accuracy; AC voltage extends to 1.0 kV at ±1% accuracy. Current measurement capability spans up to 10 A. Resistance measurements extend to 40 MΩ with ±0.5% accuracy. Capacitance ranges to 1000 µF (±2% accuracy). Frequency measurement covers 0 Hz to 100 kHz. Temperature input accepts -50°C to 700°C (-58°F to 1292°F) via thermistor probe. Display resolution provides 3.5 digits across a 4000-count dual display.
