Assistant
The OCM guides through a menu using an artificial dam-up (e.g. using a sand-
bag) to determine required characteristics. The theoretical discharge curve will
be generated automatically.
This function may be combined with the automatic mode. The theoretical set-
tings within the flow velocity monitoring area (see Fig. 9-68, No. 4).
will be verified using this method.
First ensure free discharge, then start level measurement with >ENTER<.

The OCM executes the first level measurement in free discharge. Measuring will
take 8 seconds.

After the first measuring, a dam-up of minimum 6.5 cm (12 cm are recom-
mended) must be created behind the sensor by using a sandbag or similar.
The second level measurement in the dam-up cannot be started before
"h-actual“ shows stable values.
