Program E-load
Select this mode to access the electronic-load function. Electronic load can be used as the load for
battery discharge, switching power supply or charger. It can be easily set to these discharge modes:
constant-current, constant-voltage, constant-resistance, and constant-power. With this function, the
discharge performance of the battery can be visually measured (the discharge voltage can be up to
10A), the service duration of the battery working in the constant-power (for example, by
simulating the power consumption of 10W of an electrical appliance) can be measured, and the
maximum output current of the battery working in the constant-voltage mode can be measured.
Therefore, this function very helpful.
After the electronic-load function is accessed, the interface is shown as below.

The first line indicates that the tester is working in the electronic-load mode.
The second line indicates that the current electronic-load mode is constant-current.
This tester supports four electronic-load modes:
1.
CC (constant-current): The tester automatically regulates the operating current to make it
constant.
2.
CV (constant-voltage): The tester automatically regulates the operating voltage to make it
constant.
3.
CR (constant-resistance): The tester automatically regulates the operating current to ensure
that the ratio of voltage to current is constant, and enables the electronic-load to simulate a
fixed resistor with the resistance set.
4.
CP (constant-power): The tester automatically regulates the operating current to ensure that
the product of current and voltage, namely power, to be constant.
