The TL8KC1 is a Kelvin test lead that is useful when measuring leaded capacitors, inductors, and resistors. Cable length is approximately 16 inches (40.64 cm). When used with the 880, the guarded lead reduces the effect of lead impedances and contact resistance thus minimizing measurement errors and improving accuracy especially in the lower impedance range. The TL8KC1 is an included accessory with the model 880.
