Quick Start (P001 to P010)

P001 Operation
Note:
Default values are indicated with an asterisk (*) in the parameter tables, unless
explicitly described.
Sets the type of measurement required for the application. (This affects the local LCD
only: the primary variable for HART is controlled by P201.)
To measure how full the vessel is, select Level. The reading can be returned as level or as
volume:
• for a level reading, ensure P050 is set to 0: the reading returns the distance from
process empty level (Empty) to the current level
• for a volume reading, select a vessel shape at P050, and set volume parameters
051 to 055 as required
To measure how much space remains in the vessel, select Space:
• Space returns a reading for the distance between current level and process full
level (Span)
To measure the distance from the transducer face to the current level, select Distance.
0 Instrument out of service.
Level returns material level referenced from Empty (process empty level). The
1 * reading is returned in volumetric units if parameters 050 to 055 are set to enable
Values
this.
2 Space returns material level referenced from Span (process full level).
3
Distance returns material level referenced from the transducer face.
