- It is not equipped with a charger, you can use the phone charger for Android to charge it.

Description:
True four-wire 1Khz AC sinusoidal battery internal resistance meter 0.00001Ω-200Ω range. It can measure lead acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, nickel metal hydride, nickel cadmium, button battery, etc. Using ZR function to measure internal resistance below 5 milliohms is more accurate.

Attention:
The above data is in the range of 5%-95% of the gear position. If it is not within this range (less than 5% gear range range, or greater than 95% gear range range), the error may be greater than the above accuracy.

Functions:
1.The voltage internal resistance is measured on the same screen at the same time, and the measurement is rapid and stable.
The minimum resolution can reach 0.01 milliohms, which is convenient for testing large capacity, high discharge rate and low internal resistance batteries. The range can reach 200 ohms, and can measure low-capacity small-current high-internal resistance batteries such as button batteries and 9V laminated batteries.

2.The voltage and internal resistance functions have manual automatic range function respectively.
The automatic range switching is stable and fast, the measurement display is updated 4 times per second, and the range can be basically locked at a time of about 1S to stabilize the display. The HOLD function helps you lock the display, making reading more convenient.

3. Dot Matrix LCD Screen.
The combination of large and small fonts shows the measurement results clearly and displays rich contents. Setting menu is rich in content.

4. 2 Display Modes.
The normal mode displays the internal resistance and voltage on the same screen, and the sorting mode displays the internal resistance voltage and the classification and counting of batteries of various levels.

5. 3-level Battery Grading Detection.
By setting the voltage internal resistance classification value, the batteries can be grouped.

6. Rechargeable.
A reserve power interface is reserved to expand larger capacity.

7. Built-in charging management circuit.
Two charging currents of 200mA and 400mA can be set.

8. Energy Saving Function.
Can set 5-60min shutdown delay. When there is no operation or input, the ultra delay automatic shutdown. 5-30min delay can be set to enter low power consumption mode. When there is no operation or input, the ultra delay automatic shutdown.

9. Low Voltage Protection of Battery.
When battery voltage is lower than 3V, it will automatically shut down, and low voltage alarm when it is turned on.

10. Convenient and stable manual calibration and zero return function.
There is no need to open the meter, only the precision resistance can be used to calibrate the internal resistance function. Each range is calibrated separately without affecting each other. Press and hold the HOLD key to activate the one-key resistance zeroing function ZR (ZERO R), which can reduce the error in the measurement of low resistance (for example, less than 5 milliohms) and help improve the accuracy of the measurement of a few milliohms.

11. Built-in factory range calibration information.
Calibration settings can be restored at any time, without fear of manual calibration failure.

12. The backlight brightness can be adjusted.
The lighting time can be set. Can choose to close, press, and constant light mode. Brightness 10%-99%, time 5S-60S.

13. More external testing tools are available.
In addition to classic probe test line, Kelvin clips and cylindrical battery test stand are also available. Various improvements have been made to the probe test lead, and replacement parts are provided with the test lead.

14.High cost performance, not only suitable for personal use but also suitable for factory incoming inspection.
