The TA038 adaptor is used to connect a BNC current clamp to the PicoScope 3425 Differential Oscilocope. First fit the adaptor to one of the BNC inputs on the oscilloscope's front panel, then insert the adaptor's grounding plug into one of the ground sockets on the front panel.

It is important to ground the current clamp using the procedure just described. Most current clamps have an internal metal case that readily picks up electromagnetic noise from the environment, and if the case were not grounded, this noise would interfere with the signal.
