2.Press the RED (+) or BLUE (–) button to select a higher or lower value.

3.Press both buttons to select Pv = P.

Notes:

•When PV is set to 1, settings cannot be changed using push-button adjustment.

•Many settings cannot be changed using push-button calibration when PV = P.

If PV = 0, TV0 is selected for PV, URV, LRV, USL, LSL, Damping, and Highest/Lowest recorded value. The units are implicitly1 pF.

If PV = 1, TV1 is selected for PV, URV, LRV, USL, LSL, Damping, and Highest/Lowest recorded value. The units are user definable but only by HART.

If PV = P, TV0 is selected: however, the values for PV and URV are displayed in %; LRV, USL, LSL, are blanked out with - - - -; all other fields are identical to that of TV0.
