High Precision 4 Wires Internal Resistance Tester YR1030+
For Li-ion/ LiFePo4/ Ni-MH/Lead-Acid/Ni-Cd Battery
1.This with customized English Menu and
English user’s manual
2.The tester test resistance from 0.01mΩ — 200Ω
3.The tester test voltagse MUST under 28V
The 4 wires 1Khz AC battery internal resistance tester with 0.01mΩ—200Ω range. It can measure lead acid/lithium ion/lithium polymer/ lithium iron phosphate/alkaline/dry battery, nickel hydrogen, nickel cadmium, button battery and so on. Use ZR function to measure the internal resistance below 5mΩ with higher accuracy.

Features:
1. The voltage internal resistance is measured simultaneously,and the measurement is rapid and stable.
With a minimum resolution of 0.01 milliohms, it is convenient to test large-capacity, high-discharge-rate, low-resistance internal resistance batteries. With a range of up to 200 ohms, it can measure low-capacity, low-current, high-internal-resistance batteries such as button batteries and 9V laminate batteries.
2. The voltage and internal resistance functions have manual or automatic setting functions.
The automatic range  is stable and rapid. The measurement display is updated 4 times per second, and the stable display of the range can be locked in about 1 second. The HOLD function helps you lock the display and make reading easier.
3. The use of dot matrix LCD screen.
The combination of size and type, that is, the measurement results are clearly displayed and the contents are rich.
4. 2 display modes.
The common mode displays the internal resistance and voltage in the same screen, and the sorting mode shows the internal resistance voltage and the classification and counting of the batteries in each grade.
5. Has a three-level battery detection.
The battery can be grouped by setting the voltage internal resistance classification value.
6. Built-in lithium polymer rechargeable battery.
And more reserved a backup power interface, can expand more capacity.
7. Built-in charge management circuit.
200mA and 400mA charging currents can be set.
8. Energy-saving features.
Can set 5-60min shutdown delay. No operation and input, super delay automatically shut down. It can set 5-30min delay to enter low power mode. No operation and input, super delay automatically shut down.
9. Battery low voltage protection.
When the battery voltage is lower than 3V, it will automatically shut down and the low voltage alarm will be generated when the battery is turned on.
10. Convenient and stable manual calibration, zero return function.
No need to open the meter, just use precision resistors to calibrate the internal resistance function. Each range is individually calibrated and does not affect each other. Pressing the HOLD button a long time starts a ZR (ZERO R) function, which reduces the error when measuring low resistance (eg 5 milliohms or less), helping to improve the accuracy when measuring several milliohms of resistance.
11. Built-in factory calibration information.
The 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, always light mode. Brightness 10% – 99%, time 5S – 60S
