Help with hks boost guage calibration

Hi abot strange this one. Ever since I've had my car my hks boost guage never sits on the zero on I turn my ignition on, the dial tests itself every time it put my ignition on (needle moves all the way to 2.5 bar then all the way back down to -1.5bar then then goes back up to 0 where it should stop) but it never stops on the zero just above. So my boost gauge says it's boosting more than it is, compared to my hks ecv.

It's got a few buttons on it, but can't seem to set it to zero. Anyone know how to do it or know of a guide of any kind? Cheers
