Newbie here, is this multimeter repairable?

[SubmarinerKevin]

I am wondering if this is repairable (Radio Shack Auto Range Analog Meter, Cat. No. 22-216).  Multiple solder balls fell out of the case when I opened it.  Someone wisely removed the batteries.  I have no history of it, only the user manual in PDF form.  It looks like there may be marker, it rubbed off the solder but not the board when I used a fingernail on it.  Is this impossibly difficult for a newbie?  I have solder, banana plugs, etc.  I am mainly wanting to learn so I can increase my technical competency as a field technician.  Might not be able to be in the field forever, so increasing the technical skill is important to me in case I have to live an office life.  Also this would be a huge achievement for me.  So just be honest, am I shooting for the moon here?  Thanks in advance.

Oh, it turns on but I immediately turned it off and took out the batteries because, y'know, scared.

Is it repairable? How should we know?    You haven't even stated whether it is broken at all, never mind what the malfunction is. All you've said is that some solder balls fell out, and while that's an indication of sloppy manufacturing, it's not indicative of a failure.

Thank you for your honest response.  I need to get a new fuse as the old one was wrapped in foil (and blown).  I'm afraid it will blow the fuse again but hopefully this is a working meter.

Do you understand what a multimeter's fuse does? They can't blow because of a fault in the multimeter. They blow because of user error! (99% of the time, at least. The remaining 1% is from a circuit wildly misbehaving and pulling far more current than expected.)

sure they were solder and not ball bearings?

  Most of the Radio Shack stuff was of extremely poor quality so I won't spent much time trying to fix it. Add to that that Radio Shack has been out of business for several decades now and that means that that meter is probably quite old.  My advice is to to do a quick check and if it doesn't work then pitch it.  Today you can buy a much better digital meter at Harbor Freight or Amazon for about $10. For rough work I'm still using a small digital meter that Harbor Freight used to give out for free if you made any purchase. I've been using it for about 15 years and it actually works quite well but I did replace the original cheap crappy leads with something better.

That's a cool and unusual meter. There weren't many auto-ranging FET handheld analog meters. Only others I know of were Sanwa/Tenma

I wouldn't throw it away.
