Testing the samples!

A project log for Fluke 8060a Custom LCD

I've had a number of 8060s with failed displays and always wanted to design a replacement... so I did!

I sent my custom LCD plan off to a few different manufacturers, some I never heard back from but I did finally get a quote I was comfortable with.  After finalizing some details regarding order quantity and price, and actually paying for the samples, it was a not-too-long wait for them to arrive.  I was a happy guy when the samples arrived!

Included in my quote were new elastomeric strips, but I messed up one dimension of the strip and they didn't fit, so I need to re-measure and get new samples of those.  Apparently you're supposed to allow some extra percentage for the eventual compression of the strip, but I allowed too much.  Live and learn.

In any case, I was able to re-use the original elastomer from the display - which happened to be the older round/hollow elastomer vs the newer pink foam sided strip that seems to be more common nowadays.  As this was the first LCD I'd ever designed and had manufactured, I was over the moon when I popped my first sample onto the meter and powered it up... I immediately saw the power on test with all segments on, and breathed a very happy sigh of relief!

I was pretty pleased with how it came out - especially since I'd never attempted this before!  The digits are a little taller and a little skinnier - more like the Fluke 83/5/7 iii series, but I think they look good on the 8060a.  The font I chose is a touch larger than the original but is clear and easy to see.  Considering I didn't take an exact copy from the manual or a photo - which would have been easier than drawing it all myself - I quite like it!

Now I've got to wait for new elastomers and get to fitting some replacement LCDs in my remaining meters.  I'll eventually make these available for sale, but I'm a little ways off yet.
