PicoBNC+ Resistance Test Lead — Dynamic Resistance & Diode Testing
Description
The TA432 PicoBNC+ resistance test lead from Pico Technology enables automotive technicians to perform dynamic resistance measurements and diode testing with PicoScope oscilloscopes. Featuring a 2m Y-configuration with 4mm non-shrouded connections and an active current source, the TA432 works exclusively with PicoBNC+ equipped models for automatic recognition and guided test integration.
The TA432 has a total lead length of 2m in a Y configuration, with the non-PicoBNC+ ends being 1m in length and terminated in a 4mm non-shrouded connection. The lead contains an active current source and is intended to be used only on unpowered components and wires.
