Material: electrical componentsColor: see picturesNew update:1. The test current range varies from 0.20-9.99A to 0.10-9.99A.2. The lower limit and end voltage range changes from 1.0-25.0V to 0.9-28.0V.3. Support non-operational voltage indicator.4. Increase the support of four wires for load mode testing, with an independent four-wire voltage check indicator.5. The LED indicator setting digit will change to the current flashing setting digit indication. Features: Cause sterility new new design, simple and versatile loading! Automatic memory function with all parameters, it is very suitable for the automatic assembly of the power supply aging cabinet in the latest version sale, a little larger size and upgrade the fan to the original 5020 Delta high-speed dual fan, more cooling redundancy, more suitable for long hours! Note: This product is a professional test equipment, requiring the user to have basic electronics (example: users should understand what is the meaning of Ah voltage and current, etc.), or you may not be able to use the device properly, Probably the wrong cause of unnecessary damage caused by the loss of the test device! Power Requirements: DC12V voltage (actual voltage 11-14V) current is not less than 0.5A power, the power will be displayed inadequate Err6Note: the default power supply is not includedSpecifications:Operating Modes: Single-mode constant current (CC)Discharge Current: 0.10-9.99A stepper 0.1A or 0.01AMaximum discharge current error: 0.7%-0.01aMaximum capacitance test error: 0.5A 2.5%, 2A 1.5%, 5A and above 1.2%Offline voltage range (termination): 0.9-28.0V. Step 1V or 0.1V Discharge Voltage: 1.00-30.00V Maximum Voltage Measurement Error: 1%+-0.02V Can Max 9.99A 6V and 20V with the only open 3.00A)Highest Battery Test Statistic: 999.9Ah or 9999Wh, get the value hold test (the first value for those who stop the condition))Board Size: 60W 100mm*70mm*57mm (visible fan board about 12mm)Hole Positioning: 60mm*88mm diameter 3.2mm 5mm pedestal already installedFan Control: intelligent control fan (depending on the radiator fan can be stepless automatic temperature)Protection: overheating protection "otP", transient overvoltage protection "oPP", overpressure protection "ouP", reverse polarity, abnormal power supply voltage protection. Instructions::A: Mode settings (factory default setting for load mode): hold the start-stop button (red button) to keep the tester energized at the same time until the key is released, showing fun * when, turning the knob to change the setting, "Fun1" for load mode, "Fun2" Battery capacity test mode. Press the start and stop button on the buzzer after setting up, also set the "bEon" buzzer by turning the knob to open or the buzzer "bEoF" closes after setting press the button again to start and stop at the tester restart. Digital Illustration Setting:II: Load Mode:1. Turn the 12V power supply into the load mode, ensuring in the standstill state ("RUN" does not light up, otherwise press the start-stop button to turn off the load) connected to the power supply under test to the input power of the test port (P+P-), pay attention not to take wrong polarity2. Set the current and lower voltage knob, rotate the knob to set the value of the current setting position, and then press the buttonKnob to change the setting digit, the digital middle two digits on the right side of the indicator, and the VA digital indicator at the same timeSpecify the current set position.3. Press the start-stop switch, the load started to work, the lights "RUN", the power supply is applied to the circuit under test is set to enter the discharge current, while the upper one displays the actual input load voltage, when the voltage drops below the set limit voltage, the "RUN" LED flashes and is accompanied by a short audible alarm.4. The test procedure can be modified at any current, and if you want to modify a lower voltage to stop the load, you can modify it. Note: When in the alarm state, it can only carry a small current does not increase! Automatic tester, high power down function to save enough to save a set of parameters and start the state when the state again after the transmission power completes before power failure and restore data.3: Battery capacity test mode:1. The battery test should be fully charged with a special charger2. Give the tester is powered to battery capacity test mode, connect the battery current line to the positive and negative terminals of P+P if you use the test four-terminal cable, while the four-wire interface to the positive and negative voltage test handle is connected to the V+V.3 port. Turn the knob to set the discharge current and discharge voltage (referring to two specific methods: 2 description), one press after setting the start and stop switch, battery tester and first-line detection, automatic identification 2-4 line (JS-2.4 2-wire identification presentation JS4 identification, if error please stop the test and check the wiring), then input the
