3.4.5 Open Circuit Mode [Words 1 – 8 (Bits 12 & 13)]
The open circuit mode determines the fail-safe data value each channel is to default to in
the event of an open circuit condition. The table below lists the available options.
Table 3-7 (Open Circuit Mode)
Bit 13 Bit 12 Open Circuit Mode:
0
0 Zero analog value on broken input.
0 1 Set analog value to Max scale on broken input.
1 0 Set analog value to Min scale on broken input.
1 1 Previous Value
3.4.6 Disable CJC [Words 1 – 8 (Bit 14)]
This bit is used to disable CJC compensation for the associated channel.

This field is only used if the input type is a thermocouple and the
format is not a CJC format. No compensation is performed on the
thermocouple when disabled.
3.4.7 Temperature Units [Words 1 – 8 (Bit 15)]
This bit enables Celsius or Fahrenheit for the associated channel.
Note: If the associated channel is not configured for an RTD or
thermocouple, the temperature units have no effect.
