Note
• Setting P001 resets Span (P007), unless Span has previously been set to a different
value. Span is set to Empty distance minus 110% of Blanking, unless Operation is set to
distance measurement (P001=3). In this case, Span is set to the same value as Empty
(P006). Default blanking distance is 0.3 m (1 ft).
• Changing P001 may reset Output Function (P201): this applies to HART only.

P003: Measurement response
Set response time to filling/emptying rate (P003: Measurement Response)
Set P003 to a measurement response speed just faster than the maximum filling or emptying
rate (whichever is greater).
Parameter
Use a setting just faster than the maximum filling or emptying rate (whichever is greater).
Slower settings provide higher accuracy: faster settings allow for more level fluctuation.

*
Level returns material level referenced from Empty (process empty level).
The reading is returned in volumetric units if parameters P050 to P055 are
set to enable this.
2
Space returns material level referenced from Span (process full level).
3
Distance returns material level referenced from the reference point.
