Determining the fitting's K-factor with a calibration procedure (Teach-In)
The device calculates the medium's flow rate in the pipeline with the K-factor for the fitting used.
The function TEACH V. or TEACH F. is a calibration process (Teach-In) for determining the fitting's K-
factor. The K-factor can also be entered,
see chapter 8.6.3 "Entering the K-factor for the fitting
(406090) used", page 40.
The calibration procedure is applied either in relation to a known volume (TEACH V.) or in relation to the
current flow rate (TEACH F.), as measured with a reference instrument.
NOTE!
Prior to Teach-In:
Calibrate the flow rate zero point (
see chapter 8.7.2 "Calibrate the flow rate zero point", page 67).
Check that the KW value for the sensor has not been changed (
see chapter 8.7.4 "Changing the sen-
sor's KW value", page 70).
