Using the Autozero Channel
The NI 9211E has an internal autozero channel for measuring the
offset error. If the ambient temperature of the NI 9211E is less than
15 °C or more than 35 °C, use this channel to read the offset error.
Subtract the offset error from the data read from each NI 9211E
thermocouple input channel. Refer to the software help for
information about using the autozero channel. Visit
