The UNI-T UT505A 1000V Handheld Insulation Resistance Tester is a professional electrical testing instrument designed for insulation resistance measurement, electrical safety testing and diagnostic applications. It supports insulation resistance test voltages from 50V to 1000V and provides a maximum insulation resistance measurement range of up to 200GΞ©.
Combining insulation resistance testing with digital multimeter functions, the UT505A provides True RMS measurement, PI/DAR analysis, low-resistance testing, AC/DC voltage measurement, continuity testing and data storage in one compact handheld instrument.
Make sure the circuit or equipment under test is properly isolated and prepared according to the applicable electrical safety procedure. Connect the appropriate test leads, probes or alligator clips.
Select the required insulation resistance test voltage of 50V, 100V, 250V, 500V or 1000V according to the equipment and testing requirement.
Connect the test leads to the required points and initiate the insulation resistance measurement. The tester provides the measured resistance value on its 6000-count display and supports additional PI/DAR measurement functions.
Use data hold, comparison measurement and the built-in data storage function to review and retain measurement results. The UT505A can store up to 99 groups of data.
The primary purpose of the UNI-T UT505A is to evaluate the insulation resistance of electrical equipment, wiring and electrical systems. Insulation resistance testing can help identify insulation deterioration and provide useful information during electrical maintenance and troubleshooting.
In addition to insulation resistance testing, the instrument combines several electrical measurement functions including DC voltage, AC voltage, low resistance and continuity. Its PI and DAR measurement capabilities make it suitable for insulation diagnostic applications where time-based resistance measurements are required.
Provides selectable insulation resistance test voltages from 50V up to 1000V for a wide range of electrical testing applications.
Supports a maximum insulation resistance range of up to 200GΞ© for high-resistance insulation testing.
Provides Polarization Index and Dielectric Absorption Ratio measurement functions for insulation diagnostic testing.
True RMS capability supports accurate AC voltage measurement for electrical measurement and troubleshooting applications.
The large 6000-count display provides clear visibility of measurement results, supported by LCD backlight and analog bar graph functions.
The auto discharge function helps discharge the test voltage after an insulation resistance measurement.
Measurement data can be stored internally, making it easier to retain and review previous test results.
The tester includes a high-voltage output alarm to provide an indication during insulation resistance testing.
The UT505A combines a dedicated insulation resistance tester with useful digital multimeter functions in a single handheld instrument. This makes it a practical choice for technicians who need more than basic resistance measurement.
The UT505A is suitable for professionals and technicians who require insulation resistance testing together with general electrical measurement functions.
Insulation resistance testing involves test voltages up to 1000V. Always follow appropriate electrical safety procedures, use suitable personal protective equipment and ensure the equipment under test is handled by qualified personnel. Observe the instrument's high-voltage output indication and allow the automatic discharge function to operate after testing.
