The adjustment function is intended to allow MFC-CB to correct an MFC or MFM that is
connected to it by making an offset and/or slope adjustment automatically.
For additional information on the calculations used by the adjustment function and how
they interact with other MFC-CB calculations, see Section 7.1.1.
Do NOT use the adjustment function to calibrate MFC-CB set point and
measurement signals. The internal calibration function should be used for this purpose
(see Section 5.2).
OPERATION
To access the adjustment function press
[SETUP]
,
<5adj>
. The display is:
Select
<1set>
to adjust the set point
adder
and/or
multiplier
or
<2measure>
to adjust the
measurement
adder
and/or
multiplier
.
The next display is (an
<s>
or
<m>
precedes the active
device channel indicator to indicate
set
or
measure
):
Edit the values as desired. Press
[ENTER]
to return to the run screen with the edited
adder
and
multiplier
values applied.
An indicator appears on the MAIN run screen whenever an
adder
and/or
multiplier
is active. The indication is by an
<a>
just to the right of the set point value for set point
adjustments and an
<a>
just to the left of the measured value for measurement
adjustments (see Section 3.1.1 for detailed run screen information).
The adjustment function flow
adder
and
multiplier
, if different from 0 and 1, alter the set
points output and readings made by the MFC-CB. The adjustment function is always
"ON", even if MFC profiles are changed. Take care not use
adders
and/or
multiplier
s unintentionally.
Making a change to an adjustment function value sets the affected device channel output
to zero.
The adjustment function is device channel specific (DEV1, DEV2).
Adders
and
multipliers
are set independently for the two device channels and the
adders
or
multipliers
on one
channel have no effect on the other channel.
