This manual provides operating instructions, safety warnings, and technical specifications for the UT UT512 Insulation Tester.
The UT UT512 is a smart micro-insulation testing instrument designed for measuring insulation resistance and voltage in field power equipment and supply lines. It features microcomputer technology, automatic voltage release, USB data transmission, and a backlight function for operation in low light. The device complies with IEC61010 safety standards and includes overvoltage protection (CAT III 600V).
The manual details the instrument's layout, button functions, and preparation steps for measurement. It covers three main measurement modes: insulation resistance (continuous, timer, and polarization index), voltage measurement (DC and AC), and comparison measurement. Safety precautions emphasize discharging circuits before testing and avoiding operation in flammable environments. This manual is written in Chinese.
