17.7 Setting the K factor
By default, the value of the K factor is 1.0000.
The K factor can be adjusted, if the measured flow rate values differ from the real values.
Instead of setting the K factor, you can calibrate it by using a teach-in procedure. See chapter 17.8 Cali

17.8 Calibrating the K factor by using a teach-in
procedure
Before any teach-in procedure, calibrate or set the offset value flow zero point of the device. See
chapter 17.5 Calibrating the offset value of the flow zero point or 17.6 Setting the offset value of the
flow zero point .
By default, the value of the K factor is 1.0000.
The K factor should be adjusted, if the flow rate values that are measured by the device differ from the
values that are measured by a reference instrument.
The K factor can be:
•
manually adjusted. See chapter 17.7 Setting the K factor .
• automatically calibrated by using a teach-in procedure depending on the flow rate.
• automatically calibrated by using a teach-in procedure depending on a known volume.
