Informatie

Overview HP 4338B Milliohmmeter is a precise, reliable, and high speed test tool for measuring low resistance. Features Low and selectable test signal current: 1 µA to 10 mA Wide measurement range: 10 µΩ to 100 kΩ 10 µΩ resolution 1 kHz ac measurement High speed measurement: 34 ms Built-in comparator Auto measurement mode ■ Precise Low Resistance Measurement Contact failure of electro-mechanical components in low current circuits is a key issue in determining these components’ reliability. The HP 4338B offers selectable low level ac test signals (1 µA to 10 mA), so now low current conditions can be characterized. A high resolution of 10 µΩ 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 thermo-electric effects across the DUT contacts. The 1 kHz ac test signal is the best solution for evaluating 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 makes it possible to construct a measurement system using an automatic handler and an 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 HP 4338B to select the appropriate test signal level and measurement range.
