My expensive multimeter has got broken plastic pins that hold the lcd disply
on the pcb.
In spite of all my efforts I can't correctly align the zebra contacts.
Is there anybody willing to explain me how to do it?
Thanks

Zebra contacts are self-aligning thats the point of them. Assuming contacts
and zebra are clean and good and gap between pcb and LCD glass is correct
then all should be well, at least one zebra contact should lie between each
pcb pads and its corresponding lcd land

With the alignment pins broken off, how do you suggest OP correctly
positions the display WRT the PCB?

I assume some stubs or marks remain where the plastic pins broke off. Drill
and glue some replacement pins , as long as within half a land of true then
should line up

Thanks all.I solved, hope for long time.
I've been luky, the dirt that was on the meter case display window was
perfectly corresponding to the dirt line on the display.
So I found the right position.
It has been not so easy to align the display on pcb, I supplied the meter
with a voltage, tried hundreds of positions until it displaied the rights
measurement.
I got help from a pair of chinese spring loaded clamps to firmly block the
display and put some drops of cyanoacrylate on corners.
Than used plenty of epoxy glue to make it stable.
The meter now works quite perfectly, only the last digit is incomplete, but
I'm happy anyway.
At least that experience has provided more knowledge to zebra gadgets.
Thanks everybody and....don't keep your meters too clean!

What brand is your meter? You can probably order parts for it if it is not
too old. When you do order parts, order new zebra strips aswell.

It's a Chauvin Arnoux. It is a good idea investigate on spares/kits.I'll do
it, thanks.
