5. MAINTENANCE, ADJUSTMENTS AND CALIBRATION

5.2.2.5 <4VALVE>

 PURPOSE

To view and adjust the device channel valve voltage signal.

See Sections 5.2.2.1 and 5.2.1 for information on MFC-CB device channel

signal calibration.

 OPERATION

To view the device channel valve voltage signal and the current valve voltage

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

channel, press <4valve>, <1view>. The display is:

1. Valve voltage value with the Valve adder and

multiplier applied (V).

2. Indication that this is a display of the Valve

signal.

3. Device channel indicator.

4. Current value of the multiplier applied to the

Valve reading.

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

to the Valve reading.

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

can be changed.

To adjust the value of the valve voltage 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 valve voltage 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.

5.2.2.6 <5CAL DATE>

 PURPOSE

To view and edit the calibration date for the MFC-CB device channel.

 OPERATION

Press [SPECIAL] and select <4cal>. After selecting the device channel,

select <5date>. The date format is YYYYMMDD.

There is only one calibration date for both device channels (DEV1 and DEV2).
