The Metrel Electrical Safety Manager is a common application for management of wide palette of Metrel’s electrical safety testers, portable appliance testers, machine testers and industrial safety testers. This application has a unified user interface with the new generation of Metrel’s instruments – same view same meaning. It enables the pretreatment for the measurements, viewing and editing of the measurement results and generation of professional reports. Depending on the instrument model or type the user can create AUTOSEQUENCEs, custom tests or single tests. They can be integrated into the custom created test structures and then uploaded into the measurement instrument.
