National Instruments SCC-TC01 Manual De Usuario

The SCC-TC Series thermocouple input modules, SCC-TC01 and 
SCC-TC02, accept input signals from B-, E-, J-, K-, N-, R-, S-, and T-type 
thermocouples. The thermocouple inputs are filtered and passed into a 
differential amplifier with a gain of 100. The output of the amplifier passes 
through a dual-pole 2 Hz filter. Each module contains thermistor circuitry, 
powered by a 2.5 V reference, to compensate for cold-junction effects. 
Each module also can detect open thermocouple circuits.

Alternatively, you can connect voltage signals up to 

±100 mV to the screw 

terminals of the SCC-TC02 and use it as a low-bandwidth millivolt-input 
module.

The following conventions are used in this guide:

Angle brackets that contain numbers separated by an ellipsis represent 
a range of values associated with a bit or signal name—for example, 
ai<0..7>.

The » symbol leads you through nested menu items and dialog box options 
to a final action. The sequence File»Page Setup»Options directs you to 
pull down the File menu, select the Page Setup item, and select Options 
from the last dialog box.

This icon denotes a note, which alerts you to important information.

This icon denotes a caution, which advises you of precautions to take to
