The derivative term changes the controller output based on the rate of
temperature change rather than the net amount of temperature change. This
will allow the controller to react to temperature change sooner. It can turn
the heater to full power before the temperature drops too much. Usually this
parameter does not need to be changed.
oth. Output high limit. The unit is percentage (%). It allows you to set the
high limit of the output. It can be used when you have an overpowered
heater to control a small subject. For example, if you have a 250 W heater
and set the oth = 40, the heater will be used as a 100 W heater (250 x 40%
= 100). User may need to change this parameter if your heater is not 250
watt and want to improve the performance. For example, set it to 50 if you
have a 200 W heater; set it to 100 if you have a 100 W heater. Larger oth
value makes the system heats up faster, but can cause temperature
overshot and fluctuation. Smaller oth increases the heat up time.
C-F. Temperature unit setting. You can set the display to either Celsius or
Fahrenheit.
APo. Auto power-off time. This parameter is defined for how long the built-in
timer will automatically shut off the controller. This mechanism will preserve
the coil life and make the system safer, in case the user forgot to turn the
power off. This timer will start to count once this controller is turned on. By
default, it is set to 60 minutes. It can be set to maximum 999 minutes, or you
can turn this function off.

PSL. Temperature Correction Coefficient, allows the user to adjust the
displayed temperature so that it can closely show the surface temperature (of
the object being heated by the coil heater) instead of the coil temperature. The
temperature sensor, a type K thermocouple, is located at the tip of the coil. The
actual temperature on the surface of the object is normally lower than the coil.
