Fluke 87 Iii Service Manual
ok... i've got a fluke 87 that was giving me display fits, missing characters,
segments of numbers, etc.
i found a fix online for it, i believe it will work for any 80 series fluke DMM.
open up the case... 3 screws on the back.
separate case halves, remove battery.
remove single screw holding inner housings on circuit board...
carefully remove bezel from around LCD display
remove the back inner housing, separating the power connection from the LCD
flex the four clips on the front inner housing, separating it from the circuit board
remove the lcd from the top inner housing.....
now the fix... lightly run a pencil eraser across the flexible connectors top and
bottom of the LCD. run pencil eraser across the connection tabs on the PCB,
two strips of them....
snap everything back together, with a new battery.
voila! works like new again. check it against a trusted meter to make sure
you didn't bump any of the calibration pots....
takes about 10 minutes to do
segments of numbers, etc.
