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).
