This unit
The Keysight U2741A is a 5.5-digit USB modular digital multimeter delivering precision measurement across voltage, current, resistance, and specialized functions. Operating at up to 100 readings per second via high-speed USB 2.0 (USBTMC-USB488 compliant), it combines standalone portability with integration capability into the U2781A chassis for scalable test systems. Its compact, notebook-sized form factor - 117 mm × 180 mm × 41 mm with bumpers and 509 g mass - suits field deployment and space-constrained lab environments.
Technical Specifications
Measurement ranges span DC voltage from 1 µVDC to 300 VDC and AC voltage from 1 µVRMS to 250 VRMS. DC current measurement extends from 1 µADC to 2 ADC; AC current from 1 µARMS to 2 ARMS. The instrument supports 2-wire and 4-wire resistance measurement, continuity testing, diode characterization, frequency measurement, and temperature sensing via optional thermistor probe. Resolution reaches 5.5 digits with basic accuracy to 0.0025%. Common mode rejection exceeds 120 dB with 1 kΩ unbalanced load; normal mode rejection exceeds 60 dB at 50/60 Hz ±0.1%. Input protection rated at 300 VDC for voltage inputs and 2 A, 250 V fast-blown fuse for current. The module draws +12 VDC at 2 A maximum. Operating temperature range: 0°C to 55°C (full accuracy: 18°C to 28°C). Operating humidity: 50% RH non-condensing, or 50–90% RH at 40°C non-condensing. Storage temperature: –20°C to +70°C. Storage humidity: 5–90% RH non-condensing.Key Features

Agilent / Keysight U2741A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight U2741A. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight U2741A faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.
