Combined (Loop/RCD Tester) Calibration
- Verifies accurate earth fault loop impedance, RCD trip-time, and supported trip-current measurements.
- Test functions are assessed against traceable reference standards to confirm reliable performance.
- Supports dependable loop and RCD testing for installation verification, maintenance, and electrical compliance work.
Combined (Loop/RCD Tester) Calibration
Combined Loop and RCD Tester Calibration verifies that your instrument accurately measures the electrical safety parameters used during installation and circuit testing. Dependable loop impedance and RCD results help electricians assess fault protection, verify disconnection performance, and confirm the safe operation of protective devices. Our technicians use precision electrical standards and traceable reference equipment to check the tester‘s supported functions across appropriate measurement points.
The calibration process includes assessment of the key loop and RCD functions available on the instrument. Depending on the tester model, these checks may include earth fault loop impedance, RCD trip time, and RCD trip current. Results are compared with known reference values to confirm measurement accuracy and reveal any deviation from the applicable performance limits.
Routine calibration helps reduce the risk of inaccurate readings influencing installation certificates, maintenance decisions, or electrical safety assessments. Regular verification supports reliable combined loop and RCD testing across domestic, commercial, and industrial installations, as well as engineering and electrical maintenance environments.
Calibration certificates and documentation
Your combined loop and RCD tester is returned in the same condition in which it was received and supplied with a due date sticker showing the next recommended calibration date. We also issue a calibration certificate and supporting records, providing clear evidence of the test functions and measurement points assessed for inspection and compliance documentation.
