Set P003 to a measurement response just faster than the greater measurement of the
maximum filling or emptying rate.
If the IQ 300 cannot keep up with the rate of level change, select a faster rate. If the
reading bounces around an average value, select a slower rate. In general, reliability is
traded for speed. Noisy applications or those with agitators tend to be more manageable
at slower response rates, as these make use of filtering, echo verification, and longer
fail-safe delay.
• filter: averages successive measurements to filter out false echoes
• echo verification: discriminates between agitator blades in motion (spurious noise) and
the target surface (true echo)
• fail-safe timer: establishes the period from the time a loss of echo (LOE) starts until the
fail-safe default (P071) is triggered. The P003 pre-set timer value can be overridden by
P070.

Setting this parameter automatically configures the offset correction, P652.
Horn antennas and waveguide/horn combinations will come from the factory with P652
pre-set and P004 set to 240
