Yes, that is a great idea, Iphone like touch screen. Somewhere else in this thread we found that those touch screens are still about 50 Euro (not counting extra electronics for processing), while I pay 15 Euro for the LCD and maybe 3 more for 2 pots.

But indeed, if touch LCD drops in price I will experiment with one :-) The other limitation is perhaps display size, and the width of a finger...

At work I make touch-screen controlled devices (well, it is my duty get the software and hardware going :-). It appears the touch screens are quite precise. It is no problem to use a regular slider / scroll control in its original size to adjust a value.

I saw this post _after_ I bought my Keithley 2100. It's unbelieveable. I started writing a review on it as soon as I got it, which I will turn into suggestion list for Keithley. I don't know what the rest of their stuff is like, but whereas my first Fluke made a big impression, this has probably put me off Keithley for life. I'm really angry that they waste keys, but put "hold" on a shifted key!

When yours is rapidly updating the display do you find it to be erratic? I mean that the display has regular pauses, like there is some kind of I/O contention or buffer filling up. It's not what I expected.

My review is nowhere near ready yet but please let me know if you think I've got it wrong so far! This is my first review of anything.

What have you compared it with to rate the electrical performance? Sadly this is the best meter I have got accuracy-wise, so I have nothing to compare it to. It would be comforting to know that I haven't completely wasted my money.
