Rung 2.0
If the degrees selector switch is switched to Fahrenheit, configure all four channels to read in
degrees Fahrenheit. The default for channel 0 is to read the ambient temperature thermocouple.
Rung 2.1
If the ambient/cabinet selector switch is switched to ambient, and the degrees selector switch is
switched to Fahrenheit, configure channel 0 to read the ambient temperature thermocouple in
degrees Fahrenheit.
Rung 2.2
If the ambient/cabinet selector switch is switched to cabinet, and the degrees selector switch is
switched to Fahrenheit, configure channel 0 to read the CJC sensor in degrees Fahrenheit.
Rung 2.3
If the degrees selector switch is switched to Celsius, configure all four channels to read in
degrees Celsius. The default for channel 0 is to read the ambient temperature thermocouple.
