Title: HELP! I lost my multimeter instructions
Post by: tmasman on October 12, 2003, 01:17:23 pm

Sorry to bother you guys again...
I bought a multimeter about a year ago & I've never even used it for anything but the continuity testing function...

Now I can't find my instruction booklet & I need to test the voltage coming from a switchable power supply (in an arcade cabinet).  I've already blown 1 fuse & really don't want to have to mess with going out to get another if I don't have to.

Can anyone tell me what setting this (pictured below) multimeter needs to be on so that I can check for the 12V & 5V coming from my power supply?

I really am cluless with this piece of equipment & I feel rather retarded having to ask, but I'd rather not screw it up from fiddling with it any more.

Thanks! (& I've already tried searching for the instruction book online to no avail...)

Radio Shack CAT. No. 22-813

Put the switch on the spot with the "V".
Put your red lead in the right lead hole.

You may have to mess with the range button (unless it automatically figures the range).

I've worked at Radio Shack for a number of years and the one thing they are good at is keeping their instruciton booklets on the web in pdf format.  Hope this link helps.

BTW, there's AC and DC voltage.  (AC is when the voltage oscillates between positive and negative continuously).   It looks like that multimeter has one setting for both, so you probably use another button to select between the two.  (if you have it set to AC and you measure a 5v PC power supply lead, it will read 0v)

Yeah... I figured it out.
It seems kinda obvious to me now though.
When selecting the "V" setting, you just press "Select" to make sure you are on the right setting (AC or DC... "~"=AC)

It was wierd at first though... I had some setting off & when I tried checking the 12V line I'd get a reading of 0.76 & 5V would read 0.1V... After reading through the manual knuttz linked to (Thank you very much by the way) I was able to figure out the settings & see it was a close enough 11.9V & the 5V was right on.

I have to say this was one of the best tool purchases I've made since starting to play with this hobby.  It's made tracking things down so easy & now that I have the manual again I can start finding some more uses for it.
