RFNT3 Universal Laptop Battery Tester Charger Discharger Capacity correction | Инструменты

Function:
*Charge:Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries.
*Discharge:Constant current discharge for double loads.
*Test:Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.
*Capacity Correction: The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.
*50% Capacity: 
CD50%: charge firstly, and then discharge to 50% capacity
DC50%: discharge firstly, and then charge to 50% capacity
*Online Functions:Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine.
*Monitoring:Battery information can be monitored via three windows.
*Control:Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands.
*Parameters:Users can set working parameters via set parameter window in Battery Manager.

Red is being discharged;
Red flash is wrong; possible reason: no current charge; discharge without current; work overtime; activation failure;
Green is charging;
Green flash indicates that the task is complete.
operating
Power-on
 
(The left and right LEDs are on, the LCD is on for 1s, and the LCD is on, and the LCD is on, and the device is powered on. , Left and right LED off), and then try to communicate with the battery; if there is battery, the LCD display battery-related information, otherwise show all 0.
 
Connect the battery
 
Use a cable that matches the battery model and confirm that the interface is oriented correctly. Make sure that the cable is in good contact with the battery and the instrument and perform other operations. When the battery is normal and connected properly, the instrument will recognize the battery and display the relevant information on the LCD.
The battery may not be identified for possible causes
The connection does not match the battery;
Interface direction;
Bad contact
0V battery needs to be activated;
The battery model that the instrument can not recognize;
Instrument malfunction or battery is bad.
 
Charge
 
Press the recharge key to start charging. LCD "Chg" and HRL flashing; LCD real-time display battery information; LED green (this is the "green LED light" shorthand.
When the connected battery needs to be activated, press the toggle key to activate. Activation time of about 40s, after the activation is automatically transferred to the normal charge. Before the activation of the instrument can not get any battery information, including voltage, current. When activated, the instrument output voltage 8000mV, current limit 200mA.
 
Discharge
 
Press the discharge button to start the discharge. LCD "Disc" flashing; LCD real-time display battery information; LED red.
 
Function menu
 
Press KeyFunc to enter the function interface, press KeyFunc continuously to switch between functions; press KeyOK to confirm the execution of the selected function. The FCC location displays the function number being executed during the execution of the function. During function execution, you can press KeyFunc to view other function numbers. If you do not press the button for 10 seconds, the function number will be displayed.
