I promised Adam i'd hook the logic analyser up to the controller. Quite tedious but i got there. Still don't quite know how to use the thing!

Also did a few measurements using the new dso on the 1000amp controller. Noticed some ringing at over 500khz measured across the switch. hmmmm .....

I like old style test gear. Nothing like hearing the big fans running up to speed and waiting for the display to warm up! These days its all colour oled displays and fancy self tests. Not the same

Now, Cole, when you shift the gear and that little needle on the ammeter goes into the red and reads 2000 Amps, that's bad.
