Select capacitance or percent mode for dynamic primary variable (PV): menu 01

a.To see the value displayed as percent, select menu 01 and press both buttons to set Pv = P.

b.To see the value displayed as pF, select menu 01 and increase or decrease the value till Pv = 0.

The SITRANS LC 500 is now ready to operate. For a table showing the different functions available, and the combinations of switch position and button presses used to carry out these functions, see page 41. For a detailed list of menu items, see Appendix A: Menu Groups on page 54.

Notes:

•During normal operation, the 4 and/or 20 mA point can be calibrated at any time.

•If the difference in the capacitance value between the 4 mA point and the 20 mA point is smaller than the minimum span value (3.3 pF), the new value will not be accepted.

•To revert to factory settings, select menu 12 and press both buttons: the display will read FAC A.
