High-definition color screen display: TFT high-definition color screen is used, the screen layout is ingenious, the function data is clear at a glance, and the visual recognition efficiency is faster and smoother. Sorting and comparison function: Eight groups of voltage and resistance values are pre-set. Whether it is batch screening of high-quality batteries or precise positioning of problem batteries, it can be completed in an for instant, greatly improving work efficiency. Full-process recording: Equipped with automatic retention of test records, so that the test results are clear at a glance, and say goodbye to vague memories. It can also be connected to a computer to export and analyze . Touch and know: The test uses a Kelvin 4-wire connection to connect and measure, avoiding the influence of wire resistance and contact resistance, and improving test accuracy. Data retention: 1-click pause, the measured data is permanently displayed. Automatic shutdown mode: you can freely choose the automatic shutdown mode or set a specific shutdown time.
