Is this multimeter "good enough"?

pretty sure that at 0.5%+2d it would have a calibration error as great as 0.6V +12V

and it wouldnt be averaging through RMS (root mean square) but in such a simple device it likely wouldnt matter much since thats a dial not a digital

if you had something to calibrate it to.....
 
WOW!

$6.95!?!?

I didn't know such multimeters existed!

Like Ice said; 5% accuracy doesn't even tell you if you're within 5% tolerance.

Even the cheap multimeters ($12) you get at Auto Parts stores are .05% accurate.

You get what you pay for. ;)

Here's what you should do: Go on eBay and get a nice Fluke. :D
 
its half a percentage accuracy not 5% ;)

so it can measure part of the range
but plus minus 0.6V on the +12V well.....

+12V....11.4V to 12.6V
+5V......4.75V to 5.25V
+3.3V...3.135V to 3.465V

if you dead on +12V without knowing which way its inaccurate and by how much
can be the whole range (making you right as well :p )
thats assuming I "translated" the calibration error range accurately to start with
 
Oh.. Haha... Oops. I missed a decimel point. ;)

Still... I have to admit.. I've NEVER seen a DMM that cheap and I've NEVER seen one with less than .05% accuracy. That's amazing. :D
 
Yea thats cheap as hell. I personaly love my fluke 83 but that sucker was like 400 bucks when I got it years ago.
