9.2 Temperature/resistance values for the NTC thermistors
The temperature probes with NTC thermistors, normally used on the PJ32 controls, feature electrical resistance which changes
according to changes in temperature. Below are the resistance values corresponding to various temperatures.
Table 9.2.2 lists 3 resistance values for each temperature:
 R
std
is the typical resistance value at the indicated temperature;
 R
min
is the minimum value;
 R
MAX
is the maximum value.
In order to be able to check probe operation, the table shows values corresponding to a number of temperatures.
