The value of the input voltage

A step input
123456keys are 10V / 1V / 0.1V step lifting key, in order to prevent misoperation damage load, lift the 10V must also press 4 and7 or4 and1to lift.
B key input
Column : the need for13.8V output voltage
According to the voltage V respectively by 138press ENT key to finish last.
Column : the need for9V output voltage
According to the voltage V by 9followed by the ENT key is complete.
Column : need to output 4.5V
According to the voltage V by 4.5Finally, press the ENT key is complete.
According to the voltage V respectively by 04.5Finally, press the ENT key and a result is the same as above.
A word with the most complex and the most simple input method the results are the same.
Prompt.

Voltage input data is greater than 300and greater than 30V, instruments do not accept input, return not set before the voltage value. When the keyboard input data do not meet the requirements or input the wrong data, need to be removed to input new data in time, press the V key, so just input voltage data delete disappeared, can enter again. If this time to withdraw from the voltage setting state, only need to press the ENT key is returned ( and to exit the voltage input must press the V button, press ENT key to exit in return ).

Voltage display window a bit word flashing, then power waiting for input the data bits.
V / ENT input confirmation light flashes, indicating apparatus in waits for the user to press the ENT button to confirm.

The value of the input current

Input current value is automatically transferred to the state apparatus constant current constant current value, when the load current is equal to and greater than the constant current value, the power from the voltage state into the automatic constant current state, current limitations in the set value to output, not cut load.
