Fluke 28 II Battery life
Janne:
Recently my Fluke started to freeze when using the beeper mode. Reads "batt" on the screen, and will not work until powered off and on again. So I figured the batteries that came with it were not very good and ran out quickly. After putting in new batteries, it now works again. But, the old batteries were not really that flat either. All measure 1.495-1.501V, and can deliver 1.5A+ into a short circuit. I thought it should be able to drain the batteries a bit further than that??
Also, with the 1.5V batteries it's just the beeper mode that makes it shut down. Everything else works(ohms measure without beeper too), even with backlight at full power.
Is there something wrong with the meter, or is the beeper mode just so dependant on fresh batteries?

According to this thread, it's a problem at least with older units. I'll have to see if it's possible to get warranty repair for my meter.

Mine does that same thing. I haven't looked at getting it repaired yet cause I got it on Ebay from an unauthorized dealer so I don't think I will have warranty on it even though it was brand new when I got it. I will do something with it soon though.

you can always ask their local distributor, its costs nothing

Was there ever a solution to this?
I recently bought a new Fluke 28 ii, and it has the same problem. It's not a big deal though.
My meter has serial number 22790xxx.
Edit:
The diode check is behaving funny too when the back-light is on level 2. My batteries are definitely fine; each cell reads 1.598V, expiration date 03-2019.
