Hi
I had a look at my 287 a while back, and discovered that, lo and behold, the infamous supercap had spilled its guts.
Today, on a whim, I took it into Fluke's UK HQ in Norwich, and had a conversation with a service engineer outside the deliveries door in the back car park - which was a bit odd. He'd never come across the problem, but apparently they don't service hand-held meters there - they're looked after in Eindhoven.
Anyway, he took it in, with my details scribbled on a scrap of paper, and promised to get back to me. I hope I see it again one day. If I do, I'll update this thread.
John
