What: /sys/bus/iio/devices/iio:deviceX/fault_ovuv KernelVersion: 5.1 Contact: linux-iio@vger.kernel.org Description: Overvoltage or Undervoltage Input Fault. The internal circuitry is protected from excessive voltages applied to the thermocouple cables. The device can also detect if such a condition occurs. Reading returns '1' if input voltage is negative or greater than VDD, otherwise '0'. What: /sys/bus/iio/devices/iio:deviceX/fault_oc 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 '1' if fault, '0' otherwise.
