I just bought 5 new Bosch. I have a pretty accurate Fluke. Just out of curiosity I measured the new and the old. 4 new were .8 and one was 1.2

The old ones were .4, .8, .6, .8, .2

So can we assume that the .2 one was the bad one or does resistance rise
as the fail, unless the element does burn out like a light bulb resulting in zero
resistance?

I just replaced ALL of mine beause I forgot about testing with a battery, although now I see that just glowing isn't all it needs to do, it needs to glow
in the proper way as well.
