^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Overvoltage or Undervoltage Input Fault. The internal circuitry
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) is protected from excessive voltages applied to the thermocouple
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) cables by integrated MOSFETs at the T+ and T- inputs, and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) BIAS output. These MOSFETs turn off when the input voltage is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) negative or greater than VDD.
