OPERATION
8.4.3
Automatic interference signal limit adjustment
The interference signal limit (TrsHld) can be adjusted automatically in many applica
-
tions.
Configuration
1. Set the level to 30%.
2. Log in to expert mode, see
3. Run EXPRT-Pulse-AutoTn in the menu.
The sensor identifies a suitable value for TrsHld.
Note:
This setting can only be used in Pulse mode.
8.4.4
Blanking interference signals in masked zone
To blank interference signals from the area above the maximum anticipated level,
a zone can be masked (dead zone). This zone starts at the process connection and
extends to the configured point. If signal values above the set limit value (TrsHld) occur
within this area, the sensor goes into the safe state and the sensor signals a !MaskZ
error.
