Manual Specifications
The Keysight 4338A milliohmmeter is a precise, reliable, high-speed test tool for measurements of low resistance.
Precise, Low-Resistance Measurement
Contact failure of electromechanical components in a low-current circuit is a key issue for component reliability . The 4338A offers selectable low ac test signals (I pA to 10 mA) . Users can now characterize low resistances of electromechanical components under low-current conditions. A high resolution of 10 pfl allows you to determine the slightest differences in contact resistance testing of relays, switches, connectors, PC board traces and cables. The 1 kHz test signal eliminates potential errors introduced by thermoelectric effects on the device-under-test (DUT) contacts. The 1 kHz ac test signal is the best solution to evaluate the internal resistance of batteries, because it avoids dc energy consumption.
High-Speed Measurements
The high-speed (34 ms), built-in comparator and HP-IB/handler interfaces make it possible to construct a measurement system using an automatic handler and external computer to minimize production test time.
Auto-Measurement Mode
When performing gross continuity testing where the test signal level is not a significant factor in the test, the auto-measurement function allows the instrument to select an appropriate test signal and measurement range setting
