Press "SET" to enter the menu. The probe parameters menu contains the pa-
rameters, DO and DG, which characterize the transfer function of the linearized
thermistor control probe. These parameters may be adjusted to improve the ac-
curacy of the bath. This procedure is explained in detail in Chapter 10.
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. Pressing "EXIT" will cause the parameter to
be skipped ignoring any changes that may have been made.

put would be 0. Normally this is set for -25.229.

This probe parameter refers to the temperature span of the probe between 0 and
100% output. Normally this is set for 186.974.
