Fluke 187 Fading Display
<< < (3/4) > >>
rsjsouza:
My 189 does not have fading, but bleeding. When something is displayed, some adjacent segments are slightly lit. I suspect the zebra strip degraded and has become slightly conductive.
BeBuLamar:
My 189 is OK but because I used it very little. Perhaps less than 100 hours since I had it in 2004. I hope it won't have the problem. I think I would use it more when I retire as  i would be working more on my own project and not company work which I use company's meters.

If you have alkaline AA's take them out.  So many pictures of leaked AAs inside meters.  I use lsd nimh Eneloops in my  187.

Especially in the 187 and 189 which don't fully power off because they have an internal clock and use about 70uA when they're "off".

The 189 also has a supercapacitor which can leak. Check it out and if there's any leakage you need to remove it before it wrecks the PCB.

Trader:
Do you have any updates?

We (Company I work for) got several Fluke Meters, most of them are 87V, some are 187/189.
We let them calibrate every year external and one of the fluke 187 came back with an "error".
So it was sorted out and now it´s mine... :)
It´s failure?
"Only" fading display as I know it from the old Fluke 87 ones.
But cleaning the solder pads won´t make it better.
What else could I clean ?
The zebra stripes ? The display itself or should I better buy new zebrastripes for it ?
Thanks in advance!

Martin
