adjustment
In both cases the output current must correspond to the respective
level.
Measure the current output and compare the value with the calcu-
lated current value.
You have to determine the permissible deviation of the values
yourself. This deviation depends on the the accuracy requirements of
your measurement loop. Determine the permissible tolerance for the
deviation.
Mode "Range monitoring"
If both levels are important for the safety function, you have to pro-
ceed according to the mode "Range monitoring".
1. Move the level to at least three points within the range limits.
Keep a holding time of 1 minute for each level before you com-
pare the measured value.
2. Move the level to a point directly above and directly below the
range limits.
Keep a holding time of 1 minute for each level before you com-
pare the measured value.
Result
In all cases the output current must correspond to the respective level.
For this purpose, you have to measure for all levels the current output
and compare the values with the calculated current values.
You have to determine the permissible deviation of the values
yourself. This deviation depends on the the accuracy requirements of
your measurement loop. Determine the permissible tolerance for the
deviation.
tomatically. Then you carry out a comparison of two character strings.

carried over correctly. This is used to check device communication.
After this process is terminated, the safety function is again ensured.
