    6.2 is proportional to the term The different manufacturers indicate the proportionality factor in a different way (see table 1). In the PC 410 the measure- ment type is indicated with the corresponding short descrip- tion (see table 1). The user can choose the unit of the volume flow in the setup-menu (l/s, m³/h, m³/s, cfm).
  • Page 22 By default, the exponent will be 0.5 as indicated in the formula. Some fan manufacturers inform explicitly in the data sheet that a special exponent has to be used for the airflow calculation. • In this case, enter the exponent indicated in the data-sheet, in the setup-menu of the PC 410. (see chapter 6.12, „exponent“).
