pressure and be ready for use.
Press this key for one second prior to gauge
usage to rezero any initial zero shift. If zero shift
is greater than programmed zero allowance, the
gauge will display O SET (blinking) for 1 sec-
ond, then return to the measure mode. To clear

ZERO/CLR button (when min/max values are
indicated). Gauge will auto advance once zeroed.
