I have an Amphenol Millivolt Commander Model 870, about 30 years old. It is
a sensitive, FET unit that uses batteries. Most of the batteries are
general AA 1.5 volt batteries (8), but 2 of the batteries are Duracell
Mercury 1.4 volt batteries (Duracell ZM9). I suppose that these batteries
are a reference voltage. Mercury batteries are no longer in use, so I used
two 1.5 volt batteries in their place.
When I turn the on and select battery test, the meter does not move. It is
supposed to move to above the Battery OK mark. Also, when I select the
positive DC, the meter pegs negative, and when I select the negative DC, the
meter pegs positive. The batteries are all new batteries, so there is not a
problem with dead batteries.
Anyone ever worked with one of these meters and can give me some insight
into the problem with it?
