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.
Level returns distance to 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 this.
Values
2 Space returns distance to material level referenced from Span (process full level).
3
Distance returns distance to material level from reference point (transducer face).

3. Set Measurement Response (P003)
1 * slow
Values 2 medium
3 fast
Set P003 to a measurement response speed
just faster than the maximum filling or
emptying rate (whichever is greater).
5. Set process empty level (P006: Empty)
Note:
• P006 and P007 are interlinked: see
notes attached to P007.

Values
Default
Empty can be set to any distance: not necessarily
the bottom of the tank.
