Thermocouple
Changes in the ambient air temperature near the front connector or a thermocouple
wire conducting heat directly to terminal junctions can cause thermal gradients.
Observe the following guidelines to minimize thermal gradients and improve the
system accuracy.
■
Use small-gauge thermocouple wire. Smaller wire transfers less heat to or
from the terminal junction.
■
Avoid running thermocouple wires near hot or cold objects.
■
Minimize adjacent heat sources and air flow across the terminals.
■
Keep the ambient temperature as stable as possible.
■
Make sure the NI-9219 terminals are facing forward or upward.
■
Keep the NI-9219 in a stable and consistent orientation.
