10. Monitor the status of input channel 0 to determine its
configuration setting and operational status.
This is useful for troubleshooting when the blinking channel
LED indicates that an error has been flagged.
If the Module Status LED indicator is off, or if the Channel 0 LED
indicator is off or blinking, refer to Chapter 8.

Channel Number ______
Configure the channel for the
input type connected to it. Valid
inputs are thermocouples and analog
input signals of ±50 mV and ±100 mV.
You can configure the channel to read
the cold-junction (CJC) temperature.
When reading the CJC temperature,
the channel ignores the physical input
signal.
