Specifications: Material: ABS Color: black Battery: 1 * lithium battery, 2500mAh (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 (less 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 shift 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:
