Default hangar 9 tachometer

how can i find out if a tachometer is reading right. i was using a hangar 9 tach just the other weekend on a saito 120 and at idle (very rich idle, trying to break it in) it read somewhere between 400 and 500. am i supposed to multiply that by 10?? it sure didnt seem as though that engine was going that fast. is there a certain way you have to hold the tach, a certain distance? what am i doing wrong here?

thanks
