Large Current Lithium Battery Charge Dischage Capacity Tester 5V 40A Fe Battery Cyclic Tester EBC-A40L Note: The voltage of the test element (battery, etc.) cannot exceed 5V. If it exceeds 5V, the circuit board will be burned out and irreversiblePositive and negative connections should not be reversedAlways use the tester within the allowed rangeIf you need the electronic version of the product manual or software, please let us know Package includes: 1 x Tester 1 x Online Line 1 x Test Line 1 x Power Cord Specifications: Name: Battery Cyclic Tester Model: EBC-A40L Voltage range: charge 0-5V, discharge 0-5V Voltage accuracy: 0.2% ± 0.03V Current range: charge 0.1-40A, discharge 0.1-40A Current accuracy: 0.2% ± 0.01A Discharge mode: CC constant current discharge/CP constant power Discharge termination: time/voltage is lower than the set limit/manual Discharge power: maximum 200W Charge mode: CV constant current constant voltage charging Charge termination: constant current is less than the set limit/manual Capacity test: 10Ah, the resolution of 0.001Ah; 10Ah-100Ah, the resolution of 0.01Ah; Above 100Ah, the resolution 0.1Ah Cooling method: fan active cooling Equipment supply: AC 220V or 110V Testing interface: The first line shows mode (CC-constant current), voltage, and current The second line shows working process, working time (in minute) and capacity (automatic switch between 0000mAh and 00.00Ah) Working process reads OFF when the test stops and DSC or CHG in testing It shows AT1 if you choose automatic charging/discharging and 1 means the step 1 of current testing A short press on the "SET" button and the display changes to power and energy In auto test of "charge-discharge-charge", you can check test results of each step by spin the "SET" knob: press the “ON” button to start discharging test (shows DSC) and one more press to stop (shows OFF) You can open setting interface by press on the "SET" button for 2 seconds in the stop state (this function is invalid when the tester being connected with the PC software) Operating instruction: 1.Connect the tester power (wire) 2.Connect the test cable and on-line cable (not required for stand-alone testing). General test will use the clip line, four-wire battery holder or USB male cable, respectively, for testing batteries with pole tabs, cylindrical batteries and power bank / power supply. The test line is generally thick line for the current line (A + A-), thin line for the voltage line (V + V-), only connect the thick line or only connect the thin line can not be tested 3.Connect the tested battery or power supply, you can see the displayed voltage on the LCD of the tester 4.Enter the setup interface through the keys and knobs of the operation interface to set up the test parameters, which can be set up directly through the software on the computer side when online 5.Test battery capacity is generally a full battery constant current discharge test, set the discharge current and termination voltage, for power bank capacity test is the same 6.Test power bank current or power supply current is also through the constant current discharge, discharge current can be set to the maximum output value of the power bank, or slightly smaller, the termination voltage is set to 4V or less, this special attention, not the output voltage of the power bank, but the test to determine what conditions to stop the voltage. After the start can be through the key / knob or software will gradually adjust the current up, when a certain current, the power bank off the output, then measured to the maximum value 7.After setting up, you can carry out specific tests. After measuring the LCD or software will have the results displayed 8.When disconnecting the power, first remove the battery or power supply under test, and then turn off or disconnect the power supply of the tester How to connect computer: 1.Apply to windows system, windows 7/10 need to use administrator privileges 2.The value of the computer port between 2-9 3.Turn on the machine first, then open the software, the port of the software needs to keep the same with my computer device manager 4.The preferred driver is 341, if 341 installation is not successful, you need to change 2303 try again
