| KernelVersion: 5.1 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Open-circuit fault. The detection of open-circuit faults, |
| such as those caused by broken thermocouple wires. |
| Reading returns either '1' or '0'. |
| '1' = An open circuit such as broken thermocouple wires |
| has been detected. |
| '0' = No open circuit or broken thermocouple wires are detected |

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