Multiple Point Correction Facto
r (continued)
Should it be necessary to return the OFS to
basic flow reporting, all correction factor
entries may be cleared by simply entering a
zero (“0”) as prompted.
It is also recommended to clear correction
factor settings when updating or entering new
settings.
4.2.7 Duct Area Data
The most basic element in volumetric
calculations is the cross-sectional area
involved.
Formula for rectangular area:
Length X Width = Area
Formula for circular area:
x R
2
= Area
Where:
= 3.1416
R
2
= Radius Squared
Be sure that the Units of Measure (UOM) of
your measurement is the same as the UOM
set in
configurations step “0”.
4.2.8 Calibration Percentage (Optional)
Calibration adjustment is not enabled for OFS
2000C models. The measurement process is
drift-free.
