Distometer is lined up at the 2mm mark

mercredi 28 octobre 2015

Hi all,

The distometer I just started using is lined up at the 2mm mark when there is no pressure on the plunger. Should I subtract 2mm from the reading, or is the reading accurate?

It looks exactly like the distometer in this picture: http://ift.tt/1kbPxje
