CJC Type
External/Custom
External will use the temperature of the fixed value. Custom CJC will
use the reading of the other channel to be the CJC value for the
thermocouple being measured. The CJC channel is designated by
selectiong the scanner settings
and designating a CJC
channel. Example: REF 1 has a Type S TC with a cold junction in an
ice bath. CJC type is set to custom and REF 2 is the designated
channel. REF 2 has a SPRT selected and the SPRT is in the ice bath.
When measurements are made for the Type S TC, it will use the
SPRT measurement as the CJC.
Fixed value of cold junction
Manually input (-20nto 100)a
The fixed value of cold junction is displayed. The defaulted fixed
value of cold junction is 20 °C, which can be manually set in
(-20~100) °C.
External Rs

The REF1 channel allows for an external resistor to be measured in
ratio from REF2 channel
