Set the input type of the temperature sensor being used. There are two types
of Temperature Control Units available: One accepts thermocouple inputs and
the other accepts platinum resistance thermometer inputs. Both types have
an "INPUT TYPE" rotary switch on the front of the Unit to set the input type.
Set the Input Type Switch to the correct setting for sensor and temperature
range being used.
The input type setting applies to all of the Unit's control loops. It is not possible
to set different input types for the different control loops.
Set the input type with the rotary switch on the front of the Unit. If this setting
is changed, the new setting will not become effective until the power is turned
ON or the Unit is restarted.
The diagram above shows the input type set for a K-type thermocouple with a
temperature range of 0.0 to 500.0 ° C.
