<#6> corresponds to the sixth of the six available
selections in the MFC profile unit screen. Enter the
number of the selection that you would like
to change. The display becomes:
Select the type of flow unit desired (see Table 3). Then select the desired unit.

3.3.5 <5ADJ> (ADJUSTMENT)
 PURPOSE
To apply an adder and/or multiplier to the MFC-CB set point and/or measurement.
 PRINCIPLE
The adjustment function gives the user the capability to mathematically adjust the set
point output and the value measured back by MFC-CB. This is accomplished by setting
an adder and/or a multiplier.
There are separate adders and multipliers for the set point and for the measurement.
The set point adder and multiplier alter the set point actually output by
MFC-CB following:
actual set point = (requested and displayed set point * multiplier) + adder
The measurement adder and multiplier alter the value measured by MFC-CB as follows:
displayed measurement = (actual measurement *multiplier) + adder
The adder is a constant that is always expressed in terms of %FS. The full scale value is
determined by the active MFC profile (see Section 3.3.1). The m
ultiplier is dimensionless.
If a K factor is active (see Section 3.2.1), the add
er and multiplier are applied after the K
factor is applied. However, if the unit of measure is electrical or %FS, the K factor is
not used.
