6.14 Calibration Parameters
The operator of the instrument controller has access to a number of the calibra-
tion constants namely the Hard Cutout, R0, ALPHA, DELTA, and BETA.
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 instrument.
Access to these parameters is available to the user so that in the event that the
controller memory fails the user may restore these values to the factory set
-
tings. The user should have a list of these constants and their settings with the
instrument manual.
CAUTION: DO NOT change the values of the instrument calibration con
-
stants from the factory set values. The correct setting of these parameters
is important to the safety, proper operation, and performance of the in
-
strument.
The calibration parameters menu is accessed by pressing “UP” from the serial
interface menu and is indicated by the following.
CAL Calibration parameters menu
Press “SET” five times to enter the menu. The calibration parameters menu
contains the parameters, Hard Cutout, R0, ALPHA, DELTA, and BETA that
characterize the resistance-temperature relationship of the platinum control sen
-
sor. These parameters may be adjusted to improve the accuracy of the
calibrator.
