1. Four operation modes: constant current operation; constant voltage operation; constant power operation; constant resistance operation2. This time, a flexible input wiring port design is adopted. Users can manually connect different adapters to achieve different measurement functions to extend the functions3. Automatically generate measurement data reports, stop voltage and time-limited discharge4. First turn off the load switch "OFF", measure the current battery no-load voltage, and then turn on the load switch "ON" through the setting key. At this time, you can read the internal resistance parameters of the current battery. The internal resistance of this table is calculated by the formula: (no-load voltage-load voltage)/current current=battery internal resistance5. Long press the setting key, and then short press the setting key when it flashes to switch to time-limited discharge for timing setting to obtain the effect of worry-free discharge aging. The time-limited discharge can be set to count down for any length of 1-99 hours and 59 minutes. When the set time is reached, the discharge will automatically stop. It can be used as a timer to turn off the constant current discharge aging functionReal-time display of internal and external dual temperature measurement data, three intelligent safety protections6. Test various USB data cables/chargers. First, use a data cable to connect the corresponding interface of the load device, and then use the DC power cable and Android cable to connect to the "Micros input detection port". Then adjust the current by setting the button to detect the voltage drop of the data cable and the performance stability of the charger.7. Test various DC power adapters, and the 2.4-inch high-definition large color screen displays data clearly.8. The four-wire wiring method, the voltage measurement is not affected by the voltage drop of the wire, making the voltage measurement more accurate.9. Easily test various data such as voltage/current/capacity of various lithium batteries/batteries.10. Long-term 180W load discharge aging test, the temperature is kept at about 50-80 degrees.11. Adopting intelligent temperature control light effect fan design, built-in large discharge tube, more powerful and more reliable, test the overall capacity of the battery, usage time, aging performance, etc.Online method:1.
