4-wire YR1035/ YR1030+ High Accuracy Fast Lithium Battery Internal Resistance Test Instrument 100V Electric Vehicle Group 18650

YR1035 battery internal resistance is a true four-wire internal resistance , 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 battery matching, battery performance testing, battery screening, etc. The hine has a compact structure and is easy to carry. It is your perfect electrician and electronic testing hine. Features: True 4-wire AC sinusoidal measurements effectively refrain the effects of test leads and contact resistance. Two function interfaces, battery sorting function. Built-in battery, phone recharger charging, low power consumption + multle power saving options. The test range is up to 200 ohms with a minimum resolution of 0.01 milliohms and le than 5 milliohms. Pre 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 battery internal resistance meter 0.00001 ohms-200 range. It can measure plumbic , lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, nickel hydrogen, nickel cadmium, on battery, etc. The ZR function measures below 5 ohms, and the internal resistance is more accurate. Specifications: Material: ABS Color: black Battery: 1 * lithium battery, 2000mAh (included) Accuracy format: ±([accuracy percentage]+[least significant digit]) Range: 20mΩ/200mΩ/2Ω/20Ω/200Ω Maximum resolution: 0.01mΩ/0.1mΩ/1mΩ/10mΩ/0.1Ω Accuracy: 0.7%+7/0.5%+5/0.5%+5/0.5%+5/0.6%+5 Display mode: 22.00mΩ (when ZR function is enabled)/220.0mΩ/2.200Ω/22.00Ω/220.0Ω In the range of 5%-95% of the gear, when it is not within this range (le than 5% of the range of the gear range, or greater than 95% of the range of the gear range), the error may be greater than the above accuracy. Voltage measurement: ±(% reading +% range) Range: 1V/10V/100V Maximum resolution: 0.00001V/0.0001V/0.001V Accuracy: 0.15+0.015/0.15+0.010/0.15+0.015 Display mode: .99999V/9.9999V/99.999V Positive and negative symmetry error ±(0.012%+5 words) Temperature drift within normal use temperature (10℃-40℃) 100ppm/℃ Maximum voltage between any terminals: 100V Display: internal resistance figures: 2000 counts Voltage figures: 99999 counts update 4 times per second Temperature: working: 10℃-40℃, storage: -20℃-60℃ internal resistance temperature coefficient: 0.1 * (prescribed accuracy)/℃ (28℃) Power consumption:
