The controller allows the operator to set the bath temperature with high
resolution, adjust the proportional band, monitor the heater output power, and
program the controller configuration and calibration parameters. The controller
may be operated in temperature units of degrees Celsius or Fahrenheit. The
controller is operated and programmed from the front control panel using the four
key switches and digital LED display. The controller is equipped with a serial RS-
232 digital interface for remote operation. Operation using the digital interfaces is
discussed in Section 10.
