CHAPTER 7 - ENGINEER'S OPERATING
FIRST TIME SPAN SIGNAL CALIBRATION
When the 1
SPAN push-button is pressed, the operation of the selected
control card is similar to when the SPAN push-button is pressed.
To carry out the first time span calibration, proceed as indicated in
Section 9 Steps (1) to (6) but push the 1
In Step (6) when the span calibration is updated, the new
sensor calibration date and the last sensor calibration date
will both be set to the current date.
On control cards configured for catalytic sensor inputs, the
sensor span signal value is recorded as the new sensor
value. This value will be used to provide sensor life monitoring
data by comparison with subsequent values obtained during
later calibrations using the SPAN button.
