Default Re: Fluke 87 display fix

Fading LCD segments are a common problem with older Fluke DMMs. I use a soft pencil rubber to clean the contacts (PCB, zebra strips and LCD) before wiping with IPA. I'm fairly sure that this method was recommended by Fluke at some point but can't now find the particular reference.

Another tip is to maintain the original orientation of the zebra strips as they tend to adopt the shape of the PCB solder pads over time.

Overall this approach seems to be effective for a period of many years.
