The Keysight 16338A Test Lead Set is a specialized accessory for low-resistance and impedance measurements, designed primarily for use with the Agilent/Keysight 4338A and 4338B Milliohmmeters. This comprehensive kit includes Kelvin clip leads (large and small IC versions), pin-type probe leads, alligator clip leads, a mating cable, carrying case, and operation/service manual. The modular design enables mixing and matching of leads to accommodate diverse Device Under Test configurations.
## Technical Specifications
• **Supported DC Voltage:** Up to ±42 Vdc maximum (superimposed)
• **Weight:** Approximately 3 lbs
• **Dimensions:** 12 × 10 × 7 inches
• **Included Components:** Kelvin clip leads (large), Kelvin IC clip leads (small, red/black), pin-type probe leads, alligator clip leads (red/black), mating cable, carrying case, operation and service manual
## Key Features
The four-terminal (Kelvin) connection method employed by the clip leads effectively eliminates lead and contact resistance effects, enabling high-accuracy low-resistance measurements. This architecture minimizes parasitic impedances in test fixtures—critical for precision impedance analysis. The lead set accommodates fine-pitch components and supports application of superimposed DC voltage up to ±42 Vdc, extending measurement capability beyond simple resistance evaluation.
## Typical Applications
• Electromechanical component characterization
• Battery resistance and impedance testing
• Cable continuity and impedance verification
• PCB trace and connection assessment
• IC lead contact resistance evaluation
## Compatibility & Integration
Primary compatibility extends to the Agilent/Keysight 4338A and 4338B Milliohmmeters. The Kelvin connection methodology represents an industry-standard technique for high-accuracy low-resistance measurements, and the modular lead configuration permits adaptation to measurement setups beyond the primary instrument family. The product is designated obsolete by Keysight.
