This unit
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.Key Features
- Continuity and diode testing with automatic lead reversal (Auto Diode)
- Math functions: relative difference and percent readings for tolerance verification
- Min/Max logging with timestamp capture for trend monitoring
- Data Hold and Auto Hold for reading stabilization
- Average mode to attenuate measurement noise
- Input overload alert with audible tone notification
- Unique terminal shutter design prevents inadvertent current terminal engagement
- Fuse check functionality
- Zero storage between function changes (Ohms, DCV, and Capacitance)
- Battery-powered operation with 30-minute auto power-off (defeatable)
Typical Applications Suitable for bench troubleshooting, field service, educational environments, and general-purpose electrical diagnostics where portability and durability are essential.
Compatibility & Integration Standard multimeter input terminals accept voltage, current, and resistance test leads. Dedicated thermistor input for temperature measurement. Part of the Keysight (Agilent) multimeter series.
Keysight / Agilent 971A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent 971A. Calibration covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Keysight / Agilent 971A faults: blown input fuse, worn input jacks, display segment failure, relay contact wear on bench DMMs. Common faults include worn input jacks (banana socket contact wear on the mA and COM terminals), blown input fuses (especially the 440 mA HRC fuse), and display segment failures. Keithley 2000/2001/2002 bench DMMs commonly develop relay contact wear affecting resistance accuracy after extended service.
