TA473 60A BNC+ Current Clamp

Post by ben.martins »

Hi all,

Hope all are well. I've put together a very short video showing a technique that we've been looking into.

It involves connecting a current clamp to the CAN H or CAN L wiring on a branch of a network. The idea is that despite the fast switching of data taking place there will be a change in current and thanks to the fast response of the TA473 we can actually pick out the current relating to the packet. Steve Smith did pick up on using a current clamp on CAN in the following post - viewtopic.php?p=98241#p98241 but we can see the limitations where there might be multiple packets.

Hopefully though you'll notice in the video that the TA473 gives enough detail to try a different technique when looking for CAN related faults.



Hope this helps and please give it a try if and when you can and let us know what you find.

Kind regards

Ben
