- Automatic detection of battery internal resistance, current and power of DC power supply and charger
- Support 4-wire and 2-wire testing methods. When measuring voltage, it is not affected by the voltage drop of the wire. When it is used to detect a battery, its voltage is more accurate, and the discharge can be stopped accurately to protect the battery. Internal use of high-power large discharge tube for discharge test. It can test the overall capacity, use time and aging performance of battery
- This professional high-end instrument has high precision, high efficiency and stable performance. Can be used for test, discharge and burn-in and test a variety of data to provide a better inspection experience
- High-quality materials: industrial-grade intelligent temperature-controlled cooling fans with powerful functions; display a variety of color screen test data
- Quality assurance: with multiple certifications
- Six operating modes: constant current operation, constant voltage operation, constant power operation, constant resistance operation, one-key measurement of internal resistance, one-key measurement of power supply
- BRT mode of automatic battery internal resistance test: Engineers research and summarize the operation logic and physical basis of countless battery internal resistance testers, and innovate again. The intelligent one-key detection of battery internal resistance results in the form of a list report truly realizes intelligence, featuring simplicity and humanization
- One-key automatic detection of DC power supply. PT mode for charger current power performance. By long pressing the menu M key to the mode flashing, wait a moment after pressing the + key for PT mode, it automatically enters into the DC power supply/charger automatic-detector mode. Plug in the power supply and charger under test, and then short press the start button, and after it automatically starts running for a period of time, its report shows 4 important numerical results, making the complicated test instantly simplified and accurate, and easy to use
- Lifetime free firmware upgrade function. The host computer OTA Bluetooth upgrade. Our engineers will continuously update the product firmware and release new firmware according to user needs to obtain better optimization and more functions, and provide lifetime free upgrade services
- Automatic generation of measurement data reports: stop voltage and time-limited discharge. In practical applications, when the discharge ends due to timing discharge or reaching the low-voltage stop discharge threshold set by the user, the system will automatically generate several important parameters of the aging and display them on the screen, so that the user can understand the current measured data
- To test small-capacity batteries; coarse and fine constant current settings. In order to test ultra-small capacity batteries, the engineer has added a selection of 10mA gear and 1mA gear in the background, to meet the precise test of constant current discharge at different precision resolutions for batteries of different capacities
- 2.4" HD color screen: The large screen supports Chinese and English display, and can display a variety of parameters. Switch between different function interfaces by buttons
- Used to test the quality of various wires. Test the charging speed and quality of charging cables and data cables. It can test various cables such as for Android Type-C cable and Mini, and test the voltage drop of the cables. Displays a variety of detection data on one screen
- Timed constant current discharge aging function: long press the setting button, wait until the indicator light flashes, then press the setting button to switch to "limited time discharge" for timing setting, so as to obtain the effect of worry-free discharge aging. The time-limited discharge can be set to any duration from 1 to 99 hours and 59 minutes. When the countdown reaches the set time, it will automatically stop discharging. This function can be used as a timer to turn off the aging effect of constant current discharge
- Test power bank capacity. We first clear the display data to zero, and then connect a power bank and the load to discharge the power bank until the power of the power bank is used up. The capacity mAh value displayed on the screen is multiplied by the ratio of lithium battery to output voltage value and charging efficiency to obtain the nominal capacity of the power bank
- Test parameters such as current, voltage and power of DC power adapter. Use the DC power supply to connect the DC power supply port of the load instrument, and then through the "set" button or knob to precisely adjust the current, you can test the voltage and rated current value of the power supply. It also ages the DC power supply for a long time. Powerful function, simple operation, convenient and quick test
- Test various cables and chargers. Can be used for testing, discharge and burn-in. First, use a data cable to connect to the corresponding interface of the instrument. In the constant current mode of the instrument, when the current is adjusted to make the voltage drop 1V less than the no-load voltage, the current value at this time is the over-current value of the data line under test
