Hi Steve its no trouble , have you re-calibrated the gauge? have you checked all connections ie unplug and re-connect? if you have i would suggest that you contact the service manager at barrus his name is Tim Bennett if his phone goes to voice mail leave a msg and hev will contact you (he is good about contacting people ) make sure that you have your obm s/n in case its requirede and the info of the back of the gauge.
Retirement very good i dont have enough time for work anymore i sit in the garden and watch the grass grow all the best for the future , and if im a bit slow answering i dont switch the computure on every day
regards
