MFC-CB™ Operation and Maintenance Manual

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

multipliers 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.
