17.8.2 Calibrating the K factor by using a teach-in procedure
depending on a known volume
→
Make sure the teach-in conditions are similar to those of the process.
To calibrate the K factor by using a teach-in procedure depending on a known volume, do the following:
→
Prepare a tank which capacity you know. To make sure to get an accurate K factor, prepare the recom-
mended volume of liquid given in Table 38 or in Table 39.
