TIF 8800 Problem

[barlyhop]

I seldom use my TIF 8800 anymore. I just tried using it recently to pinpoint a gas leak near a furnace. The "geiger" no longer sounds properly and all I get is a steady squelch no matter how I adjust the sensitivity. The unit is fully charged and I just installed a new tip with no change in operation.

The unit is 6 years old, do you think this might be repairable, an "over" charge of some kind...or?

Any ideas would be appreciated here! I seldom test for leaks anymore due to liability, but it is nice to be able to pinpoint leaks when they are obvious.

Thanks

battery is weak.

usually it was a dirty tip or the tip screen was "dented"
