# ∀ (for all) in voltmeter specification

I am working on a voltmeter and the tolerance for it is 0.25% ∀ 1 digit. I am not sure what exactly what this means. I am guessing if my value was 19.95 'for all' could mean I have a range of 19.94 and 19.96?

• You can write it as the HTML entity &forall; -- except in titles and comments, where you must paste the actual character: ∀ – Dave Tweed Jun 11 at 19:08

We often see a font error in pdf files where $$\\Omega\$$ is intended but it comes out as a W.
