4Description:
5 Open-circuit fault. The detection of open-circuit faults,
6 such as those caused by broken thermocouple wires.
7 Reading returns either '1' or '0'.

9 === =======================================================
10 '1' An open circuit such as broken thermocouple wires
11 has been detected.
12 '0' No open circuit or broken thermocouple wires are detected

18Description:
19 Overvoltage or Undervoltage Input Fault. The internal circuitry
20 is protected from excessive voltages applied to the thermocouple
21 cables by integrated MOSFETs at the T+ and T- inputs, and the
22 BIAS output. These MOSFETs turn off when the input voltage is
23 negative or greater than VDD.
24
25 Reading returns either '1' or '0'.
26
27 === =======================================================
28 '1' The input voltage is negative or greater than VDD.
29 '0' The input voltage is positive and less than VDD (normal
30 state).
