The default length of the test line is 0.5 meters. Colour:black Material:plastic Internal resistance measurement: Precision format: ± ([precision percentage] + [least significant digit] Range minimum resolution accuracy 20mohm 0.01mohm 0.7%+7 (when ZR function is enabled) 200mohm 0.1mohm 0.5%+5 2ohm 1mohm 0.5%+5 20ohm 10mohm 0.5%+5 200ohm 0.1ohm 0.6%+5 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. Voltage measurement: Range Accuracy ± (% reading + % range) 1V 0.35+0.015 10V 0.30+0.010 100V 0.30+0.015 Positive and negative symmetry error ± (0.012% + 5 words) Temperature drift within normal use temperature (10 Celsius -40 Celsius) 100ppm / Celsius The tester test resistance from 0.01mohm--- 200ohm The tester test voltagse under 100V .It show 4 digit after decimal point Package Contents: 1 x Internal Resistance Meter 1 x probe tester line 1 x Kelvin Clip Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
