YR2050 Milliohm Meter High-Precision Handheld DC Micro Ohm Meter Low Resistance Meter Tester

Description:
This is a high-precision and cost-effective milliohm meter, which also has the functions of calculating square number, meter number and resistivity. It is suitable for testing wires such as milliohm resistance, current-sensing resistance, power cord, wire, and network cable.

Although it is not for testing battery, it can test the resistance of transformers, motors, large inductance inductors, etc., and higher accuracy can be used to detect the resistance of precision current-sense resistors.

Applications:
1. Cut a certain length, such as 1m. Measure the diameter to calculate the cross-sectional area, enter the instrument detection mode, enter the corresponding parameters, and measure the resistance of the wire to calculate the resistivity. The resistivity can determine whether the wire material is pure copper.
2. For a coil of wire, measure the diameter of the wire to calculate the cross-sectional area, enter the instrument detection mode, enter the corresponding parameters, and select the wire material, such as copper. Find out the overall resistance at both ends of the wire to calculate the length of the wire and judge whether the length of the wire is sufficient.
3. Check whether the transformer winding is qualified. In the normal mode, open the upper and lower limits, and input the upper and lower limits of resistance to test the resistance of the transformer winding.
4. Motor repair. The winding resistance of a high-power motor is extremely small. If there is a short circuit between the same winding wires, it is difficult to detect it with the resistance file of a multimeter. You can compare the resistance value of the normal winding in the normal mode.
5. Power cord detection. The quality of the three-hole power cords for household appliances on the market is uneven. You can use the detection mode to input the length and material of the power cord, such as copper, and measure the resistance to calculate the cross-sectional area of the wire.
6. Contact resistance detection, whether all kinds of connectors, telescopic probes and wiring terminals are in good contact can be judged by the resistance value.
7. Test milliohm resistance such as current-sense resistance and shunt.
