Create a Simulated Device
To run examples without the hardware installed, use an NI-DAQmx simulated device. To create a
simulated device in MAX:
1.
Launch MAX.
2.
Right-click
Devices and Interfaces»Create New
.
3.
From the dialog, select
Simulated NI-DAQmx Device or Modular Instrument
.
4.
Type
4353
in the text box at the top of the window.
5.
Select the device from the list provided.

Cold-Junction Compensation
Cold-junction compensation is the process of measuring the temperature of the screw terminal junction
for the thermocouple and applying a representative compensating voltage to the voltage measured by
the thermocouple channel. The accuracy of the cold-junction temperature measurement is a key part of
the accuracy of the overall thermocouple temperature measurement. The TB-4353 is carefully designed
to ensure high-accuracy cold-junction temperature measurements, under a variety of conditions;
however, care must be taken to ensure the best possible accuracy. Refer to the
section for guidelines to minimize thermal gradients that could impact the CJC accuracy.
Refer to the
section for the CJC accuracy specifications.
