Once a machine with an active
alarm override is selected, the
operator is asked to confirm
the cancellation of the alarm
override. Use the up and down
arrow keys to highlight
'Cancel Override' and press
"ENTER" to cancel override
on the selected machine, or
press "EXIT" to leave alarm
override activated.
3.7 Calibration
The 'Calibration' function is
used to adjust the sensor
temperature or humidity
readings if they do not agree
with a secondary measurement
device such as a mercury
thermometer, without having to
physically make adjustments
on the machine controller. The
current offsets can also be
viewed, to see if a sensor is
substantially out of calibration.
