Feature 1True four-wire 1Khz AC sinusoidal internal resistance meter 0.00001---200 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. The ZR function is used to measure the internal resistance of 5 milliohms or less. 2Note: It is forbidden to input AC signal and DC voltage higher than 100V. 3Special combination: Host and probe test line, suitable for measuring various types of batteries, good versatility. Twisted pair of wires to improve anti-interference. 4Made of high quality ABS material, sturdy, durable and long service life. 5Professional manufacturing, stable characteristics and high reliability.SpecificationItem Type: Battery Internal Resistance TesterModel: YR1035Material: ABSColor: BlackMeasurement Range: 0V-100V DC, 0.01m-200Charger: 5VProbe Test Wire Length: Approx. 75cm/29.53inchInternal Resistance Measurement:Precision format: ([precision percentage] + [least significant digit]Range minimum resolution accuracy20m 0.01m 0.7%+7 (when ZR function is enabled)200m 0.1m 0.5%+52 1m 0.5%+520 10m 0.5%+5200 0.1 0.6%+5In 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.Voltage Measurement:Range resolution Accuracy (% reading + % range)1V 0.00001V 0.35+0.01510V 0.0001V 0.30+0.010100V 0.001V 0.30+0.015Positive and negative Symmetric error (0.012% + 5 words)Temperature drift within normal use temperature (10 C -40 C) 100ppm / C .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Battery Internal Resistance Tester1 xProbe Test Wire4 xReplacement Probe NeedleNoteNote: It is forbidden to input AC signal and DC voltage higher than 100V.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
