My first Fluke 1507 lasted about 11 months. I used to carry it with me in my service truck every day.
It uses 4 "c" batteries and has a battery check function. I had used the meter on a job just checking voltage one morning, when i got to another job, i needed to check voltage again and went to use it, the screen was blank, i switched to check the batteries and it showed 100%, (i had never changed them) i switched back to the volt setting and still nothing. I retrieved another meter and went on about my business. later that day i had time to open the case and found the batteries had corroded and basically exploded, not all of them. I went thru the supply house and the meter was sent back for repair, i was issued a new meter. the new meter, which i still use did the same thing after about 9 months only this time it was not near as bad and did not ruin the meter. I now try to change the batteries every 3 months and keep it in my office in a controlled enviroment. of course its never with me when i want it.
i have several Fluke instruments with batteries and i have never had a problem with this happening to any of them except the 1507, they also stay in my truck 24/7, thru the winter, I actually think the daily temp changes are to blame. What i still dont understand is why it sayed the batts were 100%
If i have to spend the $500 again, i will buy a crank model.
I have used the 1507 on underground cable runs of up to 1800' and it has shown that the insulation has been compromised on long runs.
I use a ground fault locator once i determine the problem with the megger to pin point the break.
