5-Point position:
By setting 5 points (0 %, 25 %, 50 %, 75 %, and 100 %), the outputs can be set accordingly.
Different from 2-point setting, 5 point setting allows the end user to set 0 %, 25 %, 50 %, 75 %,
100 % to their desired positions. All 5 points should be set when using this position.
3)
Set Off position: (Old PCBs with two position slide switch does not have this position.)
If the slide switch is in this position, calibration setting cannot be adjusted. This position is used to
prevent the set-values from changing when the user mistakenly press the buttons after calibration
has been completed. Only calibration setting is restricted from this position and all other
adjustments can be done.
