Measurement Setting
7.1 Mode Setting and Measurement
series have 7 common test modes, which is CC, CV, CR, CP, dynamic, list and battery.
Press Mode key to enter mode interface, use direction key or rotaty knob to select the mode and then
press Enter key to enter the selected mode interface.
Mode Introduction
Name Function
CC Mode
No matter how the input voltage changes, the electronic load always
consumes the constant current.
CV Mode
The electronic load maintains the input voltage as the set value by
changing the current consumption.
CR Mode
The electronic load is equals to a resistance, linear change the current
with the changing of input voltage to maintain a constant resistance
load.
CP Mode
The electronic load consumes a fixed power and the current decreases
as the voltage increases to maintain a constant power.
Dynamic Test
Set two different current values, the electronic load can step through the
two values.
List Test
It can only set up to 16 stepes with different load modes, the customizable
step mode and the upper and lower limit of test judgement, list test file
with save function.
Battery Test
CC/CR/CP can discharge the battery under test, it will automatically stop
when it meets cut-off condition and display the battery capacity.
7.1.1 CC Test (Constant Current Test)
In CC mode, no matter how the input voltage changes, the electronic load always consumes the constant
current.
Select CC mode in mode interface, press Enter key to enter CC mode and input current value;
Press ON key, the electronic load will in load state and the indicator will be illuminated;
Press ON key again to stop the load and the indicator will be extinguished.
