The maximum of power input is 5 digits, reserve 3 decimal points.

[CR] Constant Reentrance Mode
Under [CR] mode, electronic load be equivalent to constant resistance.
[CR] mode can efficiently simulate constant voltage source, it may not reach expecting
effect for the measurement of constant current source. Due to there is feedback circuit in
inner of constant current source to keep current constant, it may cause load be unable to
operate, then electronic load will keep state of shock adjust, and make it unstable, using
[CV] mode is the most effective way to measure constant current source.
According to the formula R=U/I: if the input voltage V is increasing, current I will be
forced to increase to keep resistance constant.
