2. Set P001: Operation (measurement mode)
Notes:
• Setting P001 resets Span (P007), unless Span has previously been set to a different value.
• Changing P001 may reset Output Function (P201): this applies to HART only.
Value
1 *
Level returns distance to material level referenced from Empty (process empty level). The
reading is returned in volumetric units if parameters 050 to 055 are set to enable this.
2 Space returns distance to material level referenced from Span (process full level).
3
Distance returns distance to material level from reference point.

3. Set P003: Measurement Response
Set P003 to a measurement response speed
just faster than the maximum filling or
emptying rate (whichever is greater).
