The Seaward 283A951 Calibration Checkbox is a simple verification tool for UK electricians and PAT testing technicians who need to routinely confirm the accuracy of their portable appliance testers (PAT testers). Recognised by the IET Code of Practice, it provides a quick and safe way to check that your PAT tester is operating within expected parameters before carrying out compliance testing.
Designed for use with the Seaward Supernova Elite, the calibration checkbox is also compatible with other PAT tester brands, making it a practical addition to any PAT testing kit used for electrical safety inspections in commercial and industrial environments.
Why use a calibration checkbox during PAT testing?
Regular accuracy checks help ensure reliable test results and reduce the risk of failed audits or incorrect pass or fail decisions. The Seaward calibration checkbox allows technicians to carry out these checks on site in seconds without specialist calibration equipment or downtime.
