The UT522 model offers a resistance measurement range up to 4000Ω and a voltage range up to 400V, and supports both the simple 2-wire method and the more accurate 3-wire method. Thanks to manual range selection, a clear backlit display, and features such as result hold and bad contact indication, the device is well-suited for daily field work. The compact housing and battery power further facilitate mobile use.\u003c\/p\u003e\u003ch3\u003ePrecise measurements in various conditions\u003c\/h3\u003e\n\u003cp\u003eThe UT522 enables earth resistance measurement across a wide range up to 4000Ω, making it suitable for both simple installations and more demanding systems. Support for the 3-wire method increases measurement accuracy, ensuring more reliable results in professional applications.\u003c\/p\u003e\u003ch3\u003eEasy-to-read display and convenient operation\u003c\/h3\u003e\n\u003cp\u003eThe backlit LCD display makes it easy to read results even in low light. The Data Hold function allows you to freeze the result on the screen, which is useful when working in hard-to-reach places. Additionally, the device alerts you when the range is exceeded or when there is poor contact, helping to avoid measurement errors.\u003c\/p\u003e\u003ch3\u003eFunctionality tailored for field work\u003c\/h3\u003e\n\u003cp\u003eIts lightweight design and compact dimensions make the UT522 well-suited for mobile use. Automatic shut-off after approximately 10 minutes reduces battery consumption, and the low-battery indicator helps prevent unexpected interruptions in work.\u003c\/p\u003e\u003ch3\u003eSafety and reliability\u003c\/h3\u003e\n\u003cp\u003eThe device features double insulation, which enhances user safety when working with electrical installations.
