Right, but these days that can actually be automated if you're careful.
You still need a guy to plug something into the board and put an electric
screwdriver into the slot, but he just presses the button and the machine
sets the null for him.

Surely a robot arm could do that these days?

You'd think do, but I haven't seen that yet. It would be cheaper, though.

Not that I would consider it a cost effective solution though, unless a
trimmer is absolutely necessary.

Well, the alternative is using laser-trimming like Analog Devices does...
and that isn't cheap either although it's less labour-intensive.

You could eliminate the mechanical aspect by using one of those electronic
thimpots and storing the value in non-volatile memory !
