Temperature conversion value
: 10 times of a real temperature is displayed.
•
Digital conversion value
▶
If a temperature conversion value is converted into a
value within 0 to 16000, that value is a digital
conversion value.
▶
It can be used as a process value of the PID control
module.
▶
Expression
Digital conversion value = (16000/ measuring
temperature range)
