8.8 Probe Parameters
The probe parameter menu is indicated by,
PrObE
Press "SET" to enter the menu. The probe parameters menu contains the
parameters, D0 and Dg, which characterize the resistance-temperature
relationship of the thermistor control probe. These parameters may be adjusted
to improve the accuracy of the bath. This procedure is explained in detail in
Section10.
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" will cause the parameter to be
skipped ignoring any changes that may have been made.
8.8.1
D0
This probe parameter refers to the resistance of the control probe at 0 °C.
Normally this is set for −25.2290 ohms.
8.8.2
Dg
This probe parameter refers to the average sensitivity of the probe between 0
and 100 °C. Normally this is set for 186.9740
8.9 Serial Interface Parameters
The serial interface parameters menu is indicated by,
SErIAL
The serial interface parameters menu contains parameters which determine the
operation of the serial interface. The parameters in the menu are — BAUD rate,
sample period, duplex mode, and linefeed.
8.9.1
Baud Rate
The baud rate is the first parameter in the menu. The baud rate setting
determines the serial communications transmission rate.
The baud rate parameter is indicated by,
BAUd
Press "SET" to choose to set the baud rate. The current baud rate value will then
be displayed.
