Details about each parameter.
•
SC
: Calibration offset. The parameter is used to make the input offset to compensate for
the error produced by sensor. Each unit is 1 degree. e.g. if the temperature displays 2 °C
in ice water mixture, set SC=-2 will make the display to shown 0 degree.
•
OUT
: Output power reduction. It is expressed as a percentage value. This function will
allow you to control the maximum output power delivered by the heater. For example, if
you set Out=50 and your heater is 1000 watts, the output will use 50% of the 1000 watts
as the full output. It treats the 1000W heater as a 500W heater. When the PID algorithm
determines 50% output value, the actual power output will be 250 watts.
•
C-F
: Temperature unit setting. You can set the display to either Celsius or Fahrenheit.
