The maximum of current input is 5 digits, but the decimal point will vary according to the
I-MAX.
When I-MAX
3A, reserve 4 decimal points;
When I-MAX > 3A, reserve 3 decimal points;

[CV] Constant Voltage Mode
Under [CV] mode, electronic load will always consume enough current to make sure the
load input voltage is constant.
If your measured power supply is constant voltage source, use [CV] mode can make the
efficient measurement. [CV] mode can also efficiently simulate LED constant current
power supply.

The maximum of voltage input is 5 digits, but the NO. of decimal point will vary
according to V-MAX:
When V-MAX
18V, reserve 4 decimal points;
When V-MAX > 18V, reserve 3 decimal points.
3.2.1.3
[CP] Constant Power Mode
Under [CP] mode, electronic load will always constant power.
[CP] mode can efficiently simulate constant voltage source, it may not reach expecting
effect for the measurement of constant current source, and using [CV] mode may be more
effective for the measurement of constant current source.
According to the formula: P=U
×
I , if the input voltage V is increasing, current I will be
forced to decrease to keep power constant.
