The HP/Agilent 16089A Large Kelvin Clip Lead is a four-terminal test accessory engineered for precision low-impedance measurements on components with large terminals or leads incompatible with standard fixtures. Using Kelvin (four-terminal pair) sensing, this lead set eliminates the effects of lead resistance and inductance to deliver accurate impedance characterization across a broad frequency spectrum. The two insulated Kelvin clips secure reliably to large-diameter terminals, making it ideal for odd-shaped components and non-standard geometries.
