Controller Operation

7 Controller Operation
This section discusses in detail how to operate the instrument temperature
controller using the front control panel. By using the front panel
key-switches and LED display, the user may monitor the target temperature,
adjust the set-point temperature in degrees C or F, monitor the output
power, adjust the controller proportional band, and program the operating
parameters, program parameters, serial interface configuration, and the con-
troller calibration parameters. Operation of the functions and parameters is
shown in the flowchart in Figure 4 on page 20. This chart may be copied
for reference.
In the following discussion a button with the word "SET", "UP", "DOWN", or
"EXIT" inside indicates the panel button while the dotted box indicates the
display reading. Explanation of the button or display reading is to the right
of each button or display value.
7.1

Target Temperature

The digital LED display on the front panel allows direct viewing of the ac-
tual temperature. This temperature value is what is normally shown on the
display. The units C or F, of the temperature value are displayed at the right.
For example,
100.0 C Target temperature in degrees Celsius
The temperature display function may be accessed from any other function
by pressing the "EXIT" button.
7.2

Temperature Set-point

The temperature set-point can be set to any value within the range and
resolution as given in the specifications.
Setting the temperature involves selecting one of the eight set-points in
memory and then adjusting the set-point value.
7.2.1

Programmable Set-points

The controller stores eight (8) set-point temperatures in memory. The
set-points can be quickly recalled to conveniently set the instrument to a
previously programmed temperature set-point.
To set the temperature, first select the set-point memory. This function is ac-
cessed from the temperature display function by pressing the "SET" button.
The number of the set-point memory currently being used is shown at the
left on the display followed by the current set-point value.
