:stupid: If I'm in the wrong forum, sorry. Please move it to the correct forum if necessary.
O, I'm lost. I bought this Radio Shack Micronta Multimeter, part #22-205 through E-Bay a little while ago. I only paid $9.99 for it including shipping, so I'm not out a lot of money. The seller reported that the meter won't read anything on the 20K-Ohm resistance scale. I initially thought it had a blown resistor or diode. So, I tested all of the components, resistors, diodes, capacitors; everything. Well, as it turns out, there's absolutely nothing wrong that a new set of batteries won't fix. The meter takes a single "C" cell plus another battery. The thing is... I can't tell what that bettery is or what voltage the meter wants. The battery seems to be an integral part of the failsafe cirtuit; which explains why the one particular resistance scale won't work. It is the most susceptable to blowing by doing something stupid like applying having the meter set to measure a voltage instead of resistance.
Inside, the battery compartments are extremely clean. This meter doesn't appear to have been used much at all. Looking at the battery compartments though, the only marking that can be seen are arrows indicating polarity. I was initially thinking of one of theos 9 volt camera battereis, but I think those might be too small. It's also not a stack of button cells either. The only thing holding the batteries in place are the battery clips on the ends of their respective compartments. There is some marking on the outside of the battery compartment in white ink, but I don't think it means anything.
I need a manual... Pure and simple. Plus if I can get a schematic, that would be awesome. I've been looking for a manual for this thing, but it's so old that finding a manual, or other documtation is proving to be a challenge. So I though I'd ask here.
Does anyone here have a manual and possibly even a schematic for this little beasty? Anything at all will help though. (Well, almost anything)
Till then, I have to use this el-cheapo digital thing my wife bought me. (But that's another story) :blush:
I'm attaching a couple of pics to show the size of the battery compartment. Right next to it is the "C" cell in it's compartment. Hope these help.
Thanks again.
