10.5 Treatment of measurement errors
The tables below give typical examples of application-related meas-
urement errors.
The images in column " Error description" show the actual level as a
dashed line and the output level as a solid line.

1 Real level

Note:
If the output level is constant, the cause could also be the fault setting
of the current output to " Hold value".
If the level is too low, the reason could be a line resistance that is too
high
