To accept the new cutout set-point press "SET".
The next function is the configuration menu. Press "EXIT" to resume displaying
the bath temperature.
Controller Configuration
The controller has a number of configuration and operating options and
calibration parameters which are programmable via the front panel. These are
accessed from the secondary menu after the cutout set-point function by
pressing "SET." There are 5 sets of configuration parameters — probe
parameters, operating parameters, serial interface parameters, IEEE-488
interface parameters, and controller calibration parameters. The menus are
selected using the "UP" and "DOWN" keys and then pressing "SET".
Probe Parameters
The probe parameter menu is indicated by,
Press "SET" to enter the menu. The probe parameters menu contains the
parameters, R0 and ALPHA, which characterize the resistance-temperature
relationship of the platinum control probe. These parameters may be adjusted to
improve the accuracy of the bath. This procedure is explained in detail in the
Calibration Procedure section.
The probe parameters are accessed by pressing "SET" after the name of the
parameter is displayed. The value of the parameter may be changed using the
"UP" and "DOWN" buttons. After the desired value is reached press "SET" to set
the parameter to the new value. Pressing "EXIT" causes the parameter to be
skipped ignoring any changes that may have been made.
R0
This probe parameter refers to the resistance of the control probe at 0 °C.
Normally this is set for 100.000 ohms.
ALPHA
This probe parameter refers to the average sensitivity of the probe between 0
and 100 °C. Normally this is set for 0.00385 °C
Operating Parameters
The operating parameters menu is indicated by,
Press "UP" to enter the menu. The operating parameters menu contains the
cutout reset mode parameter,
