9 Controller Operation

This section discusses in detail how to operate the bath temperature controller using the front control panel. Using the front panel key-switches and LED dis- play the user may monitor the bath temperature, set the temperature set-point in degrees C or F, monitor the heater output power, adjust the controller propor- tional band, and program the calibration parameters, operating parameters, and serial interface configuration. Operation of the functions and parameters are shown in the flowchart in Figure 4 on page 36. This chart may be copied for reference.

In the following discussion a button with the word SET, UP, EXIT or DOWN inside indicates the panel button while the dotted box indicates the display reading. Explanation of the button or display reading are to the right of each button or display value.

9.1Bath Temperature

The digital LED display on the front panel allows direct viewing of the actual bath temperature. This temperature value is what is normally shown on the dis- play. The units, C or F, of the temperature value are displayed at the right. For example,

10.00C

Bath temperature in degrees Celsius

The temperature display function may be accessed from any other function by pressing the “EXIT” button.

9.2Temperature Set-point

The temperature set-point can be set to any value within the range and resolu- tion as given in the specifications. Be careful not to exceed the safe temperature limits of any devices inserted into the bath.

Setting the temperature involves two steps: (1) select the set-point memory and

(2) adjust the set-point value.

To protect the refrigeration system from excessive pressures, it will not operate above 50°C.

9.2.1Programmable Set-points

The controller stores 8 set-point temperatures in memory. The set-points can be quickly recalled to conveniently set the calibrator to a previously programmed temperature set-point.
