It is possible to define 2 cut-off flows for each calculation channel. They are defined in the unit of measurement of the
physical quantity selected for the calculation channel.
12.9.4 Measuring with calculation channels
Position the transducers for all activated measuring channels. The measurement will be started automatically.
12.10 Change of the limit for the inner pipe diameter
It is possible to change the lower limit of the inner pipe diameter for a given transducer type.
• Press key C. Enter the HotCode 071001 (see section 9.5).
Select the unit of measurement. Press ENTER.
All positive calculated values less than the limit, will be set to zero.
All negative calculated values that are greater than the limit will be set to zero.
Enter the damping factor. If the damping factor for the measuring channels A or B has al-
ready been entered in the program branch Parameter(see section 12.1), enter the value
0 (zero). Press ENTER.
The data logger can be activated/deactivated. Press ENTER.
Select the program branch Measuring. Press ENTER.
Activate the necessary channels. Calculation channels are activated or deactivated the
same way as measuring channels. Press ENTER.
If a measuring channel that is needed for an activated calculation channel has not been ac-
tivated, a warning will be displayed. Press ENTER.
If a calculation channel is activated, the HumanMux mode (see section 11.2.2) will be se-
lected at the beginning of the measurement and the values of the calculation channel will
be displayed.
If the AutoMux mode is selected, the measured values of the measuring channels, but not
the measured values of the calculation channels, will be displayed alternately.
Press key to display the calculation function.
Press key to display the measured values of the different channels.
Enter the lower limit of the inner pipe diameter of the displayed transducer type. Press EN-
TER to select the next transducer type.
Note! If a transducer is used below its recommended inner pipe diameter, a measurement might be impos-
sible.
