With fan control: Intelligent fan control (the fan can automatically and infinitely variable speed according to the temperature of the radiator). 4. Protection functions: overheating protection "otP", instantaneous over power protection "oPP", over voltage protection "ouP", reverse connection protection, abnormal power supply voltage protection. 5. Wide range of applications: can measure the actual capacity of the battery, test the actual power of the load and other purposes. 6. Increase the support for four-wire test in electronic load mode, with independent four-wire voltage indicator. Product parameters: Working power supply: DC12V regulated (11-13V) not less than 0.5A, the power supply is not appropriate will display Err6 Interface: 5.5 * 2.1mm round mouth inside the positive pole Operating mode: single mode constant current (CC) Discharge current: 0.10-9.99A step 0.1A or 0.01A Discharge current error: 0.7% plus or minus 0.01A Capacity test error does not exceed: 0.5A 2%, 2A 1.5%, 5A and above 1.2% Lower limit (termination) voltage setting range: 0.9-28.0V in steps of 1V or 0.1V Discharge voltage: 0.90-30.00V (subject to MOS internal resistance and other losses, the measured input 1V can support up to 6-7A current, 9.99A need to be measured when the voltage is greater than 1.3V) Voltage measurement error does not exceed: 0.8% ± 0.02V Power: 112W over power automatic current limitation (for example, for 110W, 11V can open 9.99A while in 20V can only open 5.5A) Power: 62W Automatic current limit for over power (e.g. for 60W, 9.99A at 6V and 3.00A at 20V) Battery test statistics limit: 999.9Ah or 9999Wh, reach the value to stop the test (to the first to the value of the stop condition) Product size: 110W: 122mm * 70mm * 77mm (fan protrudes from the board about 22mm) 60W: 106.5mm*70mm*57.5mm (fan protrudes from the board about 12mm) Positioning hole position: 60mm * 88mm hole diameter 3.2mm installed 5mm post (60W for copper post 110W for insulated nylon post) Operating instructions: I. Function mode setting (default factory electronic load mode): press and hold "ON/OFF" at the same time to energise the tester until the display of Fun* and then release the button, at this time to enter the function setting menu. Change the setting by rotating the knob, switch to the next step by pressing "ON/OFF", and set in the following order: 1. Mode setting "Fun1" is electronic load mode, "Fun2" is battery capacity test mode. 2. Buzzer switch setting "bEon" buzzer on, "bEoF" buzzer off. 3. Display brightness setting "Lt-1" "Lt-2" "Lt-3", three brightness levels can be selected. Finish this again press "ON/OFF" to save and exit the setting. Afterwards, the tester will restart and enter into normal working condition. Second, the electronic load mode: 1. Turn on the 12V power supply, make sure that it is in the stop state ("RUN" lamp does not light up, otherwise press the "ON/OFF" off) under the connection of the power supply under test to the power input port (P + P-), such as the use of four-wire connection, please at the same time will be If using four-wire connection method, please connect the voltage detection line to the (V+V-) socket at the same time. If the measured power supply voltage is higher than 1V, the voltage will be displayed automatically, and the "L-4" lamp will light up when it is recognised as 4-wire mode. Note: Do not touch the radiator with the screwdriver when wiring, and do not connect the negative pole anyway. 2. Set the current and lower limit voltage by knob, rotate the knob to set the value of the current setting position, press the knob to switch the setting digit, the number of the current setting position will be flashing, more than 3 seconds of non-operation will automatically exit the setup to return to the normal display of voltage and current. 3. Press "ON/OFF", the load starts to run, "RUN" lights up, the circuit applies the set discharge current to the input power supply to be measured, and at the same time displays the actual input voltage of the load on the upper line, when the voltage is lower than the set lower limit voltage, "RUN" lights up, the circuit applies the set discharge current to the input power supply to be measured, and at the same time displays the actual input voltage of the load on the upper line. When the voltage is lower than the set lower limit voltage, "RUN" lamp flashes and accompanied by a short buzzer alarm. 4. The current can be modified at any time during the
