PHILIPS PM-2504 VOLT AMP OHM METER – This unit was given to me by a friend, it is almost new, only the side bracket is lost. I turn it on and it was not working, even after insert the 6 "C" size alkaline batteries. By just cleaning the contacts with a hard rubber it was fixed. I have no specifications or manuals for it, but there are some pictures that might help someone.
I will use it as my "portable multimeter". I will ask a friend that works with leather to make a bag for it.
The two 9V batteries plug I ripped off since it was not used on the original, that was designed for 6x C size batteries. On the pictures you can see the 10 & 30 AMP shunt, in the back of the unit.
