for second display; T1 thermocouple, T2 thermocouple
or the difference between the two thermocouples
(T1-T2), when the thermometer is turned on, it is set to
T2 input can select alternate of thermocouple by second
display K/J key switch.
11. K/J Second display Input thermocouple type select
The K/J key switches the T2 input to select the
