Re: Recall notice - PowerFist Multimeter
Well if we remove temporarily from the equation the case about an accident due over current which is something more usual in the automotive repairs.
The truth is that the speed that those fuses get blown is crucial to protect and the dmm circuitry, and I am talking about some diodes near by the shunt.
Even a slow blow fuse it is capable to do damage on the dmm it self.
Up to date I have blown the 440mA Fuse twice and always accidentally, with 12V or less.
Fluke should offer and a choice for such fuses at 500V which are much cheaper.
I do not see the point people in automotive repairs or in CAT II which is the most common environments for the 90% of the electricians, to pay the price premium for 1000V fuses.
I have make some HRC fuses tear down so to see what we are paying after all.
