18th Edition Checkbox Calibration

18th Edition Checkbox Calibration

PAT Checkbox Calibration ensures your 18th Edition checkbox provides accurate reference values when verifying portable appliance testers. Reliable checkbox readings help engineers and electricians confirm that PAT testers operate correctly before carrying out appliance testing. Our technicians perform calibration using precision electrical standards and traceable reference equipment so your checkbox delivers dependable verification results.

During the calibration process, our team checks the unit against several known electrical values within its operating range. These checks confirm that the checkbox correctly simulates the test conditions used to verify PAT testers. This process also helps identify any deviation from expected reference values. As a result, you can rely on your checkbox when performing daily tester verification or routine safety checks.

Regular calibration of PAT verification equipment helps prevent inaccurate tester checks that could affect electrical safety testing or compliance procedures. Therefore, routine calibration supports reliable appliance testing across commercial buildings, industrial facilities, engineering workshops, and electrical maintenance environments.
