Calibration Parameters
The operator of the bath controller has access to a number of the bath calibra-
tion constants namely CTO, C0, CG, H, and L. These values are set at the fac-
tory and must not be altered. The correct values are important to the accuracy
and proper and safe operation of the bath. Access to these parameters is avail-
able to the user only so that in the event that the controller's 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 bath calibration constants
from the factory set values. The correct setting of these parameters is im-
portant to the safety and proper operation of the bath.
The calibration parameters menu is indicated by,

Press "SET" five times to enter the menu.
CTO
Parameter CTO sets the limit of the over-temperature cutout. This is not adjust-
able by software but is adjusted with an internal potentiometer. For the 6020
bath series this parameter should read as follows.

CTO
310°C
CO and CG
These parameters calibrate the accuracy of the bath set-point. These are pro-
grammed at the factory when the bath is calibrated. Do not alter the value of
these parameters. If the user desires to calibrate the bath for improved accuracy
then calibrate R0 and ALPHA according to the procedure given in Section 11.
H and L
These parameters set the upper and lower set-point limits of the bath. DO NOT
change the values of these parameters from the factory set values. To do so may
present danger of the bath overheating and causing damage or fire.
