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

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.
25 Reading returns either '1' or '0'.
27 === =======================================================
28 '1' The input voltage is negative or greater than VDD.
29 '0' The input voltage is positive and less than VDD (normal
