What sort of cells are they?
mcleod:
The horizontal lines on any of the Fluke scopemeters (123/192/192B/ETC) are caused by a failure of the adhesive on the ribbon cable.
I bought a 192 and 192B on ebay earlier this year that both had horizontal lines and was able to get them fixed. After doing a bit of googling on the problem I was able to figure out a way to fix it. If you are interested in repairing yours I can do a short write up, but you would have to give me a day or two to pull one of mine apart to take some pictures.
macboy:
I would have simply put the 825 ? in parallel with the 830 k? one, instead of doing surgery to remove the old resistor. You could have added the parallel resistor anywhere on the cable or even at the connector.

I would like very much to see your method. It's common for these displays to develop this problem.
