0-28V Internal Resistance Test Instrument Lithium Battery Four-Wire High Accurancy YR1030 Nickel Nickle Hydride Button Battery

    Feature:          Voltage resistance with the screen at the same time measurement, measurement quickly and steadily.      The minimum resolution of up to 0.01 milliohms, easy to test large capacity, high discharge rate low resistance battery.      Range  can be 200 ohms, can be measured button batteries, 9V laminated battery  and other low-capacity small current high internal resistance battery.      Voltage,  internal resistance test function, respectively, with manual automatic  range function. Automatic range switch stable and quick, the measurement  shows 4 times per second update, the basic can be locked in about 1S  time range stable display. HOLD function to help you lock the display,  more convenient reading.      Using dot matrix LCD screen. Size font combination, which clearly shows the measurement results, but also display rich content.      2  kinds of display mode. Normal mode with the screen display resistance  and voltage, sorting mode shows the interna resistance voltage and the  level of battery classification and counting.      Has a three-level battery rating detection. By setting the voltage resistance rating, the battery can be grouped.       Built-in charging management circuit. And can be set to 200mA and 400mA two charging current.      Energy  saving function. Can be set 5 - 60min shutdown delay. No operation and  input, the ultra-delayed automatic shutdown. Can be set to 5-30min delay  into low power mode.                                        Specifications:          Material: plastics      Color:Black      Display: LCD screen Display      Voltage measuring range: 0-28V      Internal resistancemeasuring range: 0-200Ω      Battery: 3.7V, 2000mAh                         Main parameter:          Internal resistance measurement:      Precision format: ± ([Percent of Degrees] +[minimum effective digit])      Minimum range resolution accuracy      20mΩ    0.01mΩ    0.7%+ 7(when ZR function is enabled)      200mΩ    0.1mΩ     0.5%+5      2Ω        1mΩ      0.5%+5      20Ω       10mΩ     0.5%+5      200Ω      0.1Ω       0.6%+5                              In  the gear 5%-95% range, within this range (less than 5% gear range, or  greater than 95%gear range range), the error may be greater than the  accuracy mentioned above.      Voltage measurement:      2V    0.001V    0.8%+5      20V   0.01V     0.8%+5      28V    0.1V     0.8%+5               Package Included:          1 x Internal Resistance Test Instrument      1 x Set probe test line       1 x Manual
