Did you pass Hannover customs without any hassle or did they ask you to disconnect the battery inside for security reasons? ![Rant :rant:](https://www.eevblog.com/forum/Smileys/default/rant.gif.pagespeed.ce.koOB_HE-VX.gif)
Absolutely no problem whatsoever in either direction, carrying everything as hand baggage

I suspect it helped that I needed 4 trays for the x-ray, two for the usual bags/clothing and two for electronic equipment including a small multimeter with leads. There was a long queue, and they probably guessed I would have been delighted to discuss things with them

I'm now stuck at Heathrow waiting for the coach, and I will be interested to see if the voltage is the same when I get home. Could x-rays shift anything?
Please pass on my thanks to your colleague that showed me the Tek 6R1; I missed saying goodbye.
