This unit

The Agilent/Keysight 4338B is a precision milliohmmeter engineered for low-resistance measurements across a wide range of industrial and laboratory applications. Operating at 1 kHz AC, it delivers measurement speeds as fast as 34 ms with 0.4% basic accuracy, making it suitable for high-volume testing of electromechanical components, batteries, cables, and PC boards.


Technical Specifications



  • Measurement Range: 10 µΩ to 100 kΩ

  • Resolution: 10 µΩ

  • Test Current Levels: Selectable AC signal from 1 µA to 10 mA (1 µA, 10 µA, 100 µA, 1 mA, 10 mA)

  • Test Frequency: 1 kHz

  • Maximum Applied AC Voltage: 20 mV peak

  • Measurement Speed: 34 ms minimum

  • Basic Accuracy: 0.4%

  • Parameters Measured: R, X, |Z|, L, θ

  • Power Requirements: 90–132 Vac or 198–264 Vac, 47–66 Hz, 45 VA typical


Key Features



  • Contact check function ensures reliable connections during measurement

  • Built-in comparator with HIGH, IN, and LOW settings for pass/fail testing

  • Auto-measurement mode optimized for very low resistances via AC test signal

  • Error correction maximizes accuracy across the measurement range

  • Non-volatile memory maintains operation through AC power loss

  • GPIB interface for automated testing and computer control

  • Isolated handler interface reduces ground loops in manufacturing environments


Typical Applications Electromechanical components, battery testing, cable continuity verification, and PC board resistance characterization.


Compatibility & Integration The 4338B accepts a range of test leads and accessories including the 16338A Test Lead Kit (Kelvin clip, pin, and alligator leads), 42091A 4-terminal pair short termination for calibration, 42030A standard resistor set (1 mΩ to 100 kΩ), and optional 4338B-1CM rackmount or 4338B-1CN front handle kits.

Common Agilent / Keysight 4338B faults: GPIB interface board failure, display failure, guard terminal switch contact wear, oscillator calibration drift on older analog bridges. HP 4284A and 4285A most common faults are HPIB interface board failure and display contrast loss. The internal oscillator and vector measurement circuits are highly stable and rarely fail. Wayne Kerr and GenRad bridge instruments may develop switch contact wear on decade resistance/capacitance dials.
