Commissioning
Select:
• "distance=ok" if the correct distance is displayed. Any echoes closer to the sensor will be
suppressed by the following interference echo suppression.
• "dist. too small" if the displayed distance is too small. In this case, the signal comes from an
interference echo which will be suppressed.
• "dist. too big" if the displayed distance is too large. This error cannot be cancelled by
suppressing the interference echo. This means that the following two functions are skipped.
Check the application parameters "tank shape" (002), "medium proerty" (003) and
"process cond." (004) and the "empty calibr." (005) in the "basic setup" (00) function
group.
• "dist. unknown" if you do not know the actual distance. This means that the following two
functions are skipped.
• "manual" if you want to specify the suppression area yourself in the following function.
5.7.3 Function "range of mapping" (052)

E
This function displays the suggested range of mapping. The reference point is always the sensor
membrane. This value can be edited by the operator.For manual mapping, the default value is:
0 m.
"
Caution!
The suppression range must end 0.5 m in front of the echo of the actual level. With an empty
tank, do not enter E but E – 0.5 m.
