LRV and URV

PV1 (DP) Range Values

ATTENTION

The Lower Range Value and the Upper Range Value fields for PV1 are found on the DPConf tab card.

Set the LRV (which is the process input for 4 mA dc* (0%) output) and URV (which is the process input for 20 mA dc* (100%) output) for the differential pressure input PV1 by typing in the desired values on the SCT configuration .

•LRV = Type in the desired value (default = 0.0)

•URV = Type in the desired value

(default = 100 inH2O@39.2 °F for SMV models SMA125 and SMG170)

(default = 10 inH2O@39.2 °F for SMV models SMA110)

* When transmitter is in analog mode.

•SMV 3000 Transmitters are calibrated with inches of water ranges using inches of water pressure referenced to a temperature of 39.2 °F (4 °C).

•For a reverse range, enter the upper range value as the LRV and the lower range value as the URV. For example, to make a 0 to 50 inH2O range a reverse range, enter 50 as the LRV and 0 as the URV.

•The URV changes automatically to compensate for any changes in the LRV and maintain the present span (URV – LRV).

•If you must change both the LRV and URV, always change the LRV first.
