MFC-CB™ Operation and Maintenance Manual

The calibration of the set value is used to minimize the amount of correction to

the set point based on sense measurement that is necessary to achieve the

desired set point at the MFC. This is accomplished by adjusting the set point

value using an adder and a multiplier (see Section 5.2.1). When in the set view

scree

n in the MFC calibration function, the set value displayed is the value

actually output by MFC-CB after correction iterations based on the sense

line readings. Thus, the difference between the set displayed and the set

entered is the magnitude of the correction. Use the set adder and multiplier to

minimize this value.

In normal MFC-CB operation, the actual set value may be modified by a K factor

and/or adjustment factors in addition to the calibration coefficients (see

Section 7.1). When in the set view screen of the MFC calibration function, K

factors an

d adjustment factors are deactivated.

 OPERATION

To view the device channel set value after sense line based corrections and the

current set adder (A) and multiplier (M), press [SPECIAL], <4cal>, select the

desired device channel, press <3set>, select voltage or current, press <1view>.

The display is:

1. Set value after sense line based corrections

with the Set adder and multiplier applied (V

or mA).

2. Indication that this is a Set display.

3. Device channel indicator.

4. Current value of the multiplier applied to the

Set value.

5. Current value of the adder (V or mA) applied

to the Set value.

While in the view screen, the [SET MFC] key is active so that set point values

can be changed. The set value displayed is the actual set value after sense line

based corrections (see PRINCIPLE directly above).

To adjust the value of the adder (A) and/or multiplier (M), press [ESCAPE] to

return to the view/cal screen, and then press <2cal> to access a screen in which

the values of A and M can be edited. After entering the edited values, press

[ESCAPE] and return to <1view> to view the set values with the edited

calibration coefficients applied.

See Section 5.2.1 for an explanation of adders and multipliers and their use in

adjusting electrical settings and readings.
