YR1035 batt-ery internal resistance tester is a true four-wire internal resistance tester, which can test internal resistance and voltage value at the same time, and can also be used for resistance measurement. The measurement results are displayed on the same screen. This product is suitable for batt-ery matching, batt-ery performance testing, batt-ery screening, etc. The machine has a compact structure and is easy to carry. It is your perfect electrician and electronic testing machine.

Features:
True 4-wire AC sinusoidal measurements effectively refrain the effects of test leads and contact resistance.
Two function interfaces, batt-ery sorting function.
Built-in batt-ery, phone recharger charging, low power consumption + multiple power saving options.
The test range is up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.
Press HOLD to enable the ZR function to measure internal resistance as low as 0.30-0.50 milliohms.
Handmade, the appearance of the right side is overly cautious.
True four-wire 1KHz AC sinusoidal batt-ery internal resistance meter 0.00001 ohms-200 range.
It can measure plumbic acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry batt-ery, nickel hydrogen, nickel cadmium, button batt-ery, etc.
The ZR function measures below 5 ohms, and the internal resistance is more accurate.
