Using Seaward’s free datalogger program and pressing a single download key allows test result data to be quickly and easily transferred from the PrimeTest 250+ to PC at the press of a button. Data is downloaded in a simple CSV spreadsheet format for your PAT records or alternatively the CSV data can be imported directly into Seaward’s PATGuard 3 software for more enhanced record keeping, reporting and certification.
Seaward’s unique ‘ZAP’ technology ensures that earth continuity measurements are accurate in situations where other testers struggle to provide reliable measurements, such as measuring through rust, limescale and other surface contamination.
