Connecting the Signals
Refer to the
NI 435X User Manual
for examples on how to connect to the
signals.
Connecting Thermocouples
Insert the thermocouple miniconnector to the mating miniconnector on the
TC-2190. Each miniconnector is keyed; that is, it has two spades of
different widths so that you can insert the thermocouple in only one way.
Do not force the miniconnector. If you encounter difficulty while inserting
the miniconnector, check whether the polarity is correct.
