customer password has to be entered.
Otherwise, the settings only can be watched
but not changed.
The ESC key is used for discarding changes.
Volume flow QV unit:
Using this function, the physical unit, limit
values and the upper-range value of volume
flow can be defined.
For selecting the desired function please use
the key
or
. After choosing the
Volume

function and pressing the
ENTER key, the following selection field will
be displayed.
Example:
For changing the parameter please refer to

Scaling the outputs
The measuring variable volume flow rate is
shown by the VMM as well as an analog cur-
rent output as a pulse output.
The correlation of output and flow rate is not
fixed but it can be defined by the parameters
QV LRV
and
QV URV
(see Fig).
Volume flow lower-range value:
This function allows setting the lower-range
value for volume flow QV LRV which corre-
sponds to the lower-range value for the out-
put value.
For selecting the desired function please use
the key
or
. After choosing the function
Volume flow lower-range value
and
pressing Enter, the following selection field
will be displayed:
Example:
The unit for the QV LRV is defined by the
function
Volume flow unit
.
Usually the value for QV LRV is set to 0.0
(factory default).
Volume flow upper-range value:
This function is intended to set the upper-
range value for volume flow QV URV which
corresponds to the upper-range value for the
output value.
Volume flow QV
in [USG/min]
QV LRV = 0%
+0.000000 USG/min
