54 VEGASON 54V … 56V
With the menu item " Operating range“ you
can define the operating range of the sensor
deviating from the "
Min/Max adjustment“. By
default, the operating range corresponds
otherwise to the min./max. adjustment (span).
Generally, it is better to choose the operating
range approx. 5 % bigger than the adjusted
measuring range (span) determined by the
min./max. adjustment.
In the example:
- Min. adjustment to 1.270 m,
- Max. adjustment to 5.85 m.
In the example you would have adjusted the
operating range from 1 m to 6 m.
• Save the adjustments and quit the menu
window " Limitation of the operating range“.
• Click to
„Measuring conditions“.
• In the menu window " Measuring conditions“
you click on the options corresponding to
your application.
• Confirm with
"OK“.
After a few seconds of saving during which
the adjustments are permanently saved in
the sensor, you are again in the window
"
Meas. environment“.
Sonic velocity
When measuring in a gas composition devi-
ating from air, e.g. pure nitrogen, the sonic
velocity will change. Without correction, this
would distort the measuring result.
In the menu " Sonic velocity“ the sonic velocity
can be adapted to the correct value in case
of another gas composition.
