## Long description

The Uni-T UT526 Multifunction Electrical Tester is a professional-grade instrument designed for comprehensive safety testing of electrical installations. This versatile device integrates insulation resistance measurement, RCD testing, circuit continuity testing, and AC/DC voltage measurement into a single, reliable unit. Engineered for electricians and maintenance technicians, it provides the essential data required for troubleshooting, safety inspections, and routine maintenance of power distribution and electrical equipment.
Advantages
This tester offers significant benefits for field professionals, including the ability to perform insulation resistance tests at multiple voltage levels, which is critical for identifying potential cable degradation. The inclusion of RCD testing with phase selection ensures that safety devices are functioning correctly, protecting users from electrical hazards. With a high-resolution 10,000-count display and automatic voltage detection, the device minimizes human error and speeds up diagnostic processes. Its robust design and portability make it an ideal companion for demanding work environments where reliability is paramount.
Suitable for
Testing insulation resistance in electrical wiring and equipment
Verifying the operation of residual current devices (RCD)
Checking circuit continuity in low-resistance connections
Measuring AC and DC voltage in electrical systems
Performing safety inspections on power distribution boards
This device may not be suitable for high-voltage industrial power transmission testing or specialized laboratory environments requiring extreme precision beyond the specified measurement ranges. It is also not intended for use in explosive atmospheres or environments where the device's ingress protection rating is insufficient for the conditions.

Weight: 380 g
To use the Uni-T UT526, first ensure the batteries are correctly installed and the test leads are securely connected to the appropriate terminals. Select the desired measurement function using the rotary dial. For insulation or RCD tests, ensure the circuit is de-energized where required by safety protocols. Connect the probes to the test points, observe the reading on the display, and utilize the hold function if necessary to record the data. Always verify the voltage status of the circuit before initiating resistance or continuity tests to prevent damage to the device.
What to consider before purchase
Verify that the test voltage ranges meet your specific regulatory requirements
Ensure the RCD test current settings match the devices installed in your target systems
Check if the measurement ranges for insulation and continuity are sufficient for your typical project scope
Confirm that the power supply requirements align with your preference for battery-operated equipment
Always follow local electrical safety regulations and wear appropriate personal protective equipment when working with live circuits. Regularly calibrate your testing equipment to ensure ongoing measurement accuracy.
