Description
Use this function to switch off the "Sensor corrosion" and "Sensor break" diagnostic
functions during thermocouple measurement.
This may be necessary in order to connect electronic simulators (e.g. calibrators)
during a thermocouple measurement. The accuracy of the transmitter is not
influenced by either the activation or deactivation of the thermocouple diagnostics
function.
