The 4338B milliohmmeter is a precise, reliable, high-speed test tool for measurements of low resistance. With five selectable test signal levels (1 uA, 10 uA, 100 uA, 1 mA and 10 mA), the 4338B can provide measurements under the DUT's actual operting conditions.
- 10u ohm resolution
- Contact check function
- Built-in comparator
- Auto-measurement mode
Test current levels
- Low and selectable test signal current: 1uA to 10 mA
Measurement Range / Time
- Wide measurement range: 10u ohm to 100 k ohm
- High-speed measurement: 34 ms
- 1 kHz ac measurement
The 16143B is designed to operate specifically with the 4338A/B. It is used to connect any combination of two test lead types to the 4338A/B.
