New cutout set-point
To accept the new cutout set-point press “SET”.

The next function is the configuration menu. Press “EXIT” to resume display-
ing the bath temperature.
8.11 Controller Configuration
The controller has a number of configuration and operating options and calibra-
tion parameters, which are programmable via the front panel. These are ac-
cessed from the secondary menu after the cutout set-point function by pressing
“SET.” There are 5 sets of configuration parameters - probe parameters, operat-
ing parameters, serial interface parameters, and controller calibration parame-
ters. The menus are selected using the “UP” and “DOWN” keys and then
pressing “SET”. Pressing “EXIT” in any secondary menu exits and returns to
displaying the temperature (see Figure 5 on page 36, Controller Operation
Flowchart).
8.12 Probe Parameters
The probe menu is indicated by,
Probe parameters menu
Press “SET” to enter the menu. The probe parameters menu contains the pa-
rameters, R0 and ALPHA, which characterize the resistance-temperature rela-
tionship of the platinum control probe. These parameters may be adjusted to
improve the accuracy of the bath. This procedure is explained in detail in Sec-
tion 10, Calibration Procedure.
The probe parameters are accessed by pressing “SET” after the name of the pa-
rameter 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. Press “EXIT” to skip the parameter ignoring
any changes that have been made.
8.12.1 R0
This probe parameter refers to the resistance of the control probe at 0°C.
Normally this is set for 100.000 ohms.
CO= 75C
