6.2.4 Cold junction compensation

Cold junction compensation for thermocouples is normally performed automati-
cally by means of an NTC sensor in measuring socket M0.  This sensor can be
substituted with an external measuring sensor; (see Manual, Section 6.7.3).
For especially exacting requirements (e.g. for extreme temperature gradients in
the device) special connectors are available each with its own integrated tem-
perature sensor (ZA 9400- FSx) for cold junction compensation.  These can be
used for all thermocouple types; however, they require two measuring chan-
nels.  

´#J´

 is programmed in the comments; this ensures that the temperature

sensor integrated in the connector is used for cold junction compensation.
