Description:
|
|
Overvoltage or Undervoltage Input fault. The internal circuitry
|
|
is protected from excessive voltages applied to the thermocouple
|
|
cables at FORCE+, FORCE2, RTDIN+ & RTDIN-. This circuitry turn
|
|
off when the input voltage is negative or greater than VDD.
|
|
|
|
Reading returns '1' if input voltage is negative or greater
|
|
than VDD, otherwise '0'.
