This product is suitable for quick test of wire length, resistivity, and quick judgment of the quality of power cords of motors and . Portable size and easy to carry, you can take it with you to anywhere you want to use. Although this measuring meter cannot test batteries, it can test resistances such as , motors, and large inductance inductors. The higher accuracy can be used to detect the resistance of s current-sense resistors. Easy to use: a certain length of wire, calculate the -sectional area by measuring the diameter, enter the instrument detection mode and enter the corresponding parameters, and then measure the wire resistance to calculate the resistivity. The resistivity can determine whether the wire material is pure copper. This product can be used to detect whether the transformer wg is qualified. Open the upper and lower limits in the normal mode, and input the upper and lower limits of resistance to test the resistance of the transformer wg. Specifications: Resolution: 120000 Protections fusing current: 0.5A Working temperature: 10 -40 Storage temperature: -20-60 Battery: 1 x lithium battery, 2000mAh (included) Note: This YR2050 Can't Measuring battery internal resistance . It is strictly prohibited to measure any live parts, such as AC / direct current voltage input to the test interface, which may damage the instrument. Material: Metal colour: As shown Package Contents: 1 x test instrument 1 x test clip Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
