6.7 AP/GPConf Configuration - PV2

Engineering Units

The AP/GPConf tab card displays the Low Range Value (LRV), Low Range Limit (LRL), Upper Range Value (URV) and Upper Range Limit (URL) for PV2 in the unit of measure selected in the Engineering Units field.

NOTE: Depending on the SMV transmitter model type, PV2 will measure static pressure in either absolute or gauge values.

SMV Models —SMA110 and SMA125

* Static pressure may be absolute or gauge pressure, depending on the SMV model type.

Atmospheric Offset

For SMV models SMG170, (which uses gauge pressure as PV2 input), you must measure the absolute static pressure and then enter that value in the Atmospheric Offset field.
