Quick start 1，Connect the AC100-240V or DC10-18V power supply to the corresponding input port on the back of the Q4AC. 2，The screen shows the boot logo for 2 seconds. 3，At the same time, accompanied by the sound of di-di startup. 4，After booting up, the screen enters the main interface as shown below: 5，short press [CH/Exit], the cursor will switch among the four channels in sequence. 6，Scroll [Scroll Wheel] to switch to display the voltage and internal resistance of the corresponding channel.
when all four channels are free. 9，Press [CH/Exit] to end the modification or return to the previous interface. ================================= 1. Short press [Scroll Wheel] once to confirm the function. 2. Long press [Scroll Wheel] for 2 seconds, it is the delete key function. 3. If any key is successfully operated, there will be a didi sound.
Charging settings In the main interface, select and short press [OK] to enter the charging function. If the battery selection is turned on in the main setting interface, 5 battery records can be saved, and the following interface is displayed. Otherwise, it will default to the first battery record, skip this step.
Move the cursor to “Battery Type” and press [OK] to modify the battery type, the display is as follows: The charger supports Lipo, LiHV, LiFe, Lion, NiMh, PB, 6 kinds of batteries, after choosing the battery that matches the actual battery. Short press [OK] and [CH/Exit] to take effect, and return to the previous interface.
================================================= Important 1. Choosing the wrong battery type to charge may damage the battery, the charger, and cause fire and other dangers. Please choose carefully. 2. Please do not use this product to charge the battery that is not marked with the battery type. Always follow the charging guidelines of your battery manufacturer ================================= Vocabulary explanation 1, Lipo: Often called a lithium polymer battery, a battery with a nominal voltage of 3.
2，Number of cells Move the cursor to the position of “Cells”, press [OK] to modify the number of battery cells. The display is as follows: Scroll [Scroll Wheel] to adjust the value. When set to ”Auto”, the charger will automatically identify the number of cells connected to the battery according to the battery voltage connected to the output port. Short press [OK] and [CH/Exit] to take effect and return to the previous interface.
3，Mode Move the cursor to “Mode” and press [OK] to modify the work mode, as shown in the figure below. Lipo, LiHV, LiFe, and Lion batteries can be charged and stored. NiMh, battery and PB battery can choose to charge. Short press [OK] and [CH/Exit] to take effect, and return to the previous interface. 4，End voltage（TVC） Move the cursor to “End Voltage” and press [OK] to modify the end voltage of the single-cell battery.
================================= 1, Only LiPo, LiHV, LiFe batteries can set the cut-off voltage. 2, Do not modify the cut-off voltage when you are not familiar with the battery characteristics. 3, The charging cut-off voltage can be set to a range of plus or minus 50mV of full voltage. 4, TVC: English abbreviation for terminal voltage control. ================================================== 5，Charging current Move the cursor to the Charging Current” position and press [OK] to modify the current.
================================================= Tips: 6. Please set the charging rate of 1-2C according to the battery capacity. For example, if the battery capacity is 2000mAh, please set the charging current to 2.0-4.0A. Check the guidelines of your battery’s manufacturer for correct charging instructions.
================================= Tips 1, Only NiMh battery can set the battery negative pressure value. 2, Vocabulary explanation: PeakV: When the NiMH battery is fully charged, the peak voltage of each cell drops.
Charging work When charging starts, the charger enters the working interface as shown below: Scroll [Scroll Wheel] on this interface to switch the display of the internal resistance voltage value of the corresponding channel. Short press [OK] to dynamically set the working current or stop working.
To end the charging and discharging work, short press [OK], move the cursor to [Stop], short press [OK], stop working and return to the main interface. When charging is complete or charging error occurs. A prompt box will pop up with a prompt sound.
