8.12 Calibration Parameters
The operator of the 9150 has access to the furnace calibration constants. These
values are set at the factory and must not be altered. The correct values are
important to the accuracy and proper and safe operation of the furnace. Access
to these parameters is available to the user only so that in the event the
controller memory fails, the user may restore these values to the factory settings.
The user should have a list of these constants and their settings with the manual.
Caution
DO NOT change the values of the furnace calibration constants
from the factory set values. The correct settings of these
parameters is important to the safety and proper operation of
the furnace.
