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 PV2 —Absolute Pressure
—STG170 PV2 —Gauge Pressure
PV2 Engineering Units Select one of the preprogrammed engineering units in Table 13 for display
of the PV2 measurements.

* 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.
