Does the sensor need to be cleaned?: Yes. The gauge works best with periodic cleaning.
What is the maximum operating pressure of the VG vacuum gauges? : 500 PSI
My vacuum gauge screen reads 'Calibrating', is it OK to use?: Self calibration can take as long as 30 seconds and is performed every 15 minutes or when the VG64 senses a large ambient temperature change. When the unit is self calibrating and "Calibrating" is displayed, the vacuum value will not change.
There are no numbers on the display, just 3 dashes?: 3 dashes indicate the gauge has not pulled down below 19000 microns, it is still reading at atmosphere.
Could not hold a stable reading, even when blocked off from a system. It seems to have an internal leak that prevents a consistent vacuum. Is Gauge possibly leaking, can't get accurate reading?: SUPCO VG64TL does not function in the same manner as most vacuum gauges. This is due to the more sensitive sensor used in VG64TL, it is always calculating any moisture in the system, as we as any Outgassing that is present. In light of this, once isolated, the readings will gradually increase, then level off. The leveled off micron reading will be higher than the pulled down number. If a leak was present, the reading would go all the way back up to atmosphere (ATM).
