Keep your results trustworthy with our RCD Tester Calibration service. We check trip current and trip time across the ranges electricians use daily. Then we document every result clearly, so you pass audits with confidence.
Booking takes under a minute. You choose collection or drop-off. We start work as soon as your tester arrives. Our approved team handles leading brands, including Megger, Fluke, Kewtech, Metrel, and Socket & See. Therefore you get consistent results and less downtime.
We align our checks with BS EN IEC 61557-6 for RCD test equipment. That means we verify effectiveness in TT, TN, and IT systems and confirm your tester measures correctly. We also verify 0° and 180° half-cycle timing functions where applicable. This keeps your readings reliable on site.
We confirm trip current and timing over common set points, such as 10 mA to 1 A and 20 ms to 5 s. We also check no-trip at 0.5 × IΔn and ramp functions when fitted. So you can trust pass or fail decisions in the field.
Most users recalibrate every 12 months, or sooner with heavy use. We can set reminders to help you stay compliant and organised. Finally, we return your tester with a clear label and a full certificate.
