The proportional band width is set at the factory to about 15.0°C. The propor-
tional band width may be altered by the user if he desires to optimize the con-
trol characteristics for a particular application.

The proportional band width is easily adjusted from the front panel. The width
may be set to discrete values in degrees C or F depending on the selected units.
The proportional band adjustment can be accessed within the secondary menu.
Press “SET” and “EXIT” to enter the secondary menu and show the heater
power. Then press “SET” twice to access the proportional band.

Controller Configuration

The controller has a number of configuration and operating options and calibra-
tion parameters that are programmable via the front panel. These are accessed
from the secondary menu after the proportional band function by pressing
“SET”. Pressing “SET” again enters the first of three groups of configuration
parameters—operating parameters, serial interface parameters and calibration
parameters. The groups are selected using the “UP” and “DOWN” keys and
then pressing “SET”.
