The digital display is an important part of the temperature controller because it
not only displays set and actual temperatures but also displays various bath
functions, settings, and constants. The display shows temperatures in values
according to the selected scale units
°
C or
°
F.
The control buttons (SET, DOWN, UP, and EXIT) are used to set the bath
temperature set-point, access and set other operating parameters, and access
and set bath calibration parameters.
A brief description of the functions of the buttons follows:
SET – Used to display the next parameter in a menu and to set parameters to
the displayed value.
DOWN – Used to decrement the displayed value of setable parameters.
UP – Used to increment the displayed value.
EXIT – Used to exit from a menu. When EXIT is pressed any changes made to
the displayed value will be ignored.
