Dumb question, tuners

[Cygnus x-1]

Probably a dumb question but, I've got a cheap Qwik Tune electronic tuner that I got free with a bass many moons ago, now although it's not the best peice of kit it does it's job, or so I thought, but, I was just having a look at Harmony Central today when I pressed the wrong button and got tuners. It seems my tuner isn't very well regarded and is said to be wildly inaccurate, usually too sharp.

So is there any way of testing it's accuracy at home, I dont have access to a known accurate pitch? thanks in advance, NJ
