From Makers Electronics's description
UNI-T UT620C+ Micro Ohm Meter The UNI-T UT620C+ Micro-ohmmeter is a high-precision, portable resistance meter designed to measure a wide range of resistance values, from micro-ohms to hundreds of kilo-ohms. Utilizing a four-wire (Kelvin) measurement method, it ensures accurate readings by minimizing the effects of lead and contact resistances. This makes it particularly suitable for applications requiring precise low-resistance measurements, such as testing transformer windings, motor coils, and grounding systems. Key features of the UT620C+ include a resolution as fine as 1 μΩ and an accuracy of up to ±0.1% full scale. It supports a maximum test current of 1 A and offers eight distinct resistance ranges to accommodate various testing needs. The device is equipped with a large backlit LCD display for clear visibility in different lighting conditions and can store up to 500 measurement data sets for later analysis. Its USB Type-C interface allows for easy data transfer to a PC, facilitating further data management and reporting. Designed with portability in mind, the UT620C+ is compact and lightweight, weighing approximately 480 g including its rechargeable 3.7 V, 3200 mAh lithium battery. It features an automatic power-off function to conserve battery life, activating after 15 minutes of inactivity. The device also includes safety features such as input protection up to 36 V AC/DC and an IP54 rating for dust and splash resistance, ensuring durability in various working environments. The UT620C+ is widely used in fields like telecommunications, power distribution, new energy vehicles, petrochemicals, and industrial plant grounding systems. Its combination of precision, versatility, and user-friendly design makes it an essential tool for professionals requiring accurate low-resistance measurements in both laboratory and field settings.
