(Example)
00100
= 100 °C (when the temperature sensor is a thermocouple
input)
01000
= 100.0 °C (when the temperature sensor is a platinum input)
HHHHH
= Measured temperature over-scale (input common)
LLLLL
= Measured temperature under-scale (input common)
*The measured temperature resolution of the platinum input is
ten times that of the thermocouple input.
