Hi guy's.
This may sound a dumb question but.
I'v been using a digital meter for awhile and,i decide to try a analog meter.
I know the 0 db mark is 80 db. But,were is 75 db and 70 db mark located on the meter? I did do a google search on how to read the meter.but,nothing came up that i can easy understand. so,maybe u guy's can help me out here.

The "0" mark is whatever you have set the meter to. If you set it to 60dB, then that is what the "0" mark is. 5dB above the "0" mark is 5dB above whatever the meter is set to. 5dB below the "0" mark is 5dB below whatever the meter is set to.
So, if you are trying to calibrate to 75dB you can either set the meter to 70dB and calibrate to +5dB, or you can set the meter to 80dB and calibrate to -5dB.
If that is not the answer you are looking for, I'm not sure what you are asking.

Which would technically be more accurate? Going the +5dB from 70 or the -5dB from 80? When I've checked my levels it seems that there is a difference of 1-2dB when I go back and forth, when they "should" be identical.

So, which side of "0" do you think will probably provide the more accurate reading? ;)

Neither side provides a "more accurate" reading. That is why the meters have a plus or minus 2 dB accuracy!
