To recalibrate the DuraChoice PB204L-100 pressure gauge, it should be vertical, then slightly lift up the rubber stopper on the back to relieve pressure that may have built up inside.
If a little of the gylcerin oil leaks out, simply clean it off and finally push the rubber stopper back down and make sure it's secure.
