Parameter
You subsequently determine the parameter name and
unit. These are then displayed in the measuring menu.
Parameter name
Input mode= "Parameter"
Free text Define a name for the parameter, e.g. "flow rate."
Unit of measure
Input mode= "Parameter"
Free text Determine the unit in which your parameter should be
displayed, e.g." l/min."
Lower range value
Input mode= "Parameter"
-2000.00 to 0.00
Factory setting
0.00
Your previously defined unit is additionally displayed.
The start of measuring range corresponds to a frequency
of 0 Hz.
Upper range value
Input mode= "Parameter"
0.00 to 10000.00
