9.14 Calibration Parameters
The operator of the bath controller has access to a number of the bath calibration
constants namely CTO, H, and L. These values are set at the factory and must
not be altered. The correct values are important to the proper and safe operation
of the bath. Access to these parameters is available 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 important to the safety and proper operation of
the bath.
The calibration parameters menu is indicated by,

Press “SET” five times to enter the menu.
9.14.1 CTO
Parameter CTO sets the calibration of the over-temperature cut-out. This is not
adjustable by software but is adjusted with an internal potentiometer. For the
7008 bath this parameter should read between 110 and 130.
9.14.2 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 exceeding its temperature range causing damage or
fire.
