["110W 30V Constant Current Electronic Load CC Discharge Battery Capacity Tester 0.10-9.99A 0.9-28.0V\n\nbrand new and high quality\nMaterial: Electrical components\nColor: See pictures\n\nNew Upgrade:\n1. The test current range is changed from 0.20-9.99A to 0.10-9.99A.\n2. The lower limit and termination voltage range is changed from 1.0-25.0V to 0.9-28.0V.\n3. Support non-operational voltage display.\n4. Increase the support for four-wire test in electronic load mode, with independent four-wire voltage indicator.\n5. The LED indication setting digit is changed to the current setting digit flashing indication.\n\nFeatures:\nCause sterility new New design , simple and versatile electronic load ! Automatic memory function with all parameters , is well suited for automated assembly of the power adapter aging cabinet In the sale of the latest version , slightly larger size and upgrade the fan into the original 5020 for Delta high speed dual bearing fan , higher cooling redundancy , more suitable for long hours !\nNote: This product is a professional testing equipment , requiring the user must have some basic electronic ( example: Users should understand what is the meaning of the voltage and current capacity Ah , etc. ) , or you may be unable to properly use the device , possibly mishandled cause unnecessary damage caused by the test device loss ! PPower supply requirement : DC12V voltage ( actual voltage 11-14V) current is not less than 0.5A of power, the power will be displayed inappropriate Err6\nNote: The default power adapter is not included\n\nSpecifications:\nOperating modes: single mode constant current (CC)\nDischarge current : 0.10-9.99A stepper 0.1A or0.01A\nDischarge current maximum error : 0.7% -0.01A\nThe maximum capacity test error : 0.5A 2.5%, 2A 1.5%, 5A and above 1.2%\nOffline ( termination ) Voltage Range : 0.9-28.0V. stepping 1V or 0.1V\nDischarge voltage : 1.00-30.00V\nThe maximum voltage measurement error : 1% + - 0.02V\nit can open 9.99A 6V and 20V maximum at the only open 3.00A)\nHighest battery test statistic : 999.9Ah or 9999Wh, achieve value stop testing ( first value to those who stop condition ))\nBoard size : 60W 100mm * 70mm * 57mm ( fan prominent board about 12mm)\nPositioning hole locations : 60mm * 88mm diameter 3.2mm 5mm pedestal already installed\nFan control : intelligent fan control ( according to the radiator fan can be infinitely variable automatic temperature )\nProtection: Overheat for protection \"otP\", transient overpower for protection \"oPP\", overpressure for protection \"ouP\", reverse polarity for protection, power supply voltage abnormal for protection .\nInstructions::\nA : mode settings ( default factory for electronic load mode ) : Hold down the start-stop button ( red button ) to the tester simultaneously energized until the for key is released showing Fun * When , by rotating the knob to change the setting , \"Fun1\" for electronic load mode , \"Fun2\" battery capacity test mode. Push button start and stop at the buzzer after entering the settings, also set \"bEon\" buzzer by turning the knob to open or \"bEoF\" buzzer closes After setting press the button again to start and stop at the tester restart.\nSetting Digital Illustration:\nII: Electronic Load mode:\n1. Turn on the power supply 12V boot into electronic load mode , ensuring in a stopped state (\"RUN\" does not light, otherwise the press of the start-stop switch to turn off the load ) connected to the power supply under test to the test port input power (P + P - ) , pay attention not to take the wrong polarity !\n2. Set current and lower voltage knob , turn the knob to set the value of the current setting position , then press the\nknob to change the setting digit, digital middle two digits to the right of the indicator and digital indicator VA simultaneously\ndetermine the current set position .\n3. Press the start-stop switch , load began to run , \"RUN\" lights , power is applied to the circuit under test is set to enter the\ndischarge current , while the upper display the actual input load voltage , when the voltage drops below the set limit voltage \" RUN \" LED flashes and short beep alarm buzzer accompanied.\n4. The test procedure can be modified at any current , and if you need to modify the lower voltage to stop the load can modify .\nNote:When in alarm state , can only transfer a small current does not increase !Tester automatic power-down feature to save enough to save the set parameters and run state, when the state again after power transmission will complete before the power failure and restore data.\n3: The battery capacity test mode:\n1. The test battery should be fully charged with a special charger !\n2. Give the tester is powered into the battery capacity test mode, connect the battery current line to P + P- positive and negative terminals , if you use four-wire clamp test, while the four-wire interface to the positive and negative voltage test fixture is connected to V + V -
