Product name: Metrel Electrical Safety Manager

Product type: PC SW Application


Release date: 28.2.2024




Metrel Electrical Safety Manager – a common application for the management of the new generation of Metrel’s instruments.


With this application the wide palette of Metrel’s electrical safety testers, portable appliance testers, machine testers and industrial safety testers can be now managed by one single application. This application has a unified user interface with the new generation of Metrel’s instruments – same view same meaning. It enables the pre-treatment for the related measurements, viewing and editing of the measurement results and generation of various professional reports. Depending on the model or type of the target instrument the user can create AUTO SEQUENCE® tests, custom tests or single tests. They can be integrated into the custom created test structures and then uploaded into the measurement instrument.

The downloaded measurement results can be viewed, analysed, edited and finally a professional report can be created and printed. These professional reports are based on predefined templates according to the national standards or the rules of regulatory organisations where the user enters all the needed protocol data while the measurement results are automatically inserted into the predefined forms.


This application is fully compatible with the new generation of Metrel’s multifunction testers, starting with CE MultitesterXA and EurotestXC. With limited functionality some of the predecessor models like EurotestXE or EurotestCombo are also supported.

No special installation instructions are needed.



Basic version of Metrel Electrical Safety Manager is a free SW. Advanced functionality is defined by the licence key(s) which is(are) always related to the serial number of the instrument. Depending on the licence key and purchased set a specific advanced features like upload, creation of various professional reports, post processing or languages are enabled or disabled.

Licence keys for additional functions are usually localised and can be ordered via Metrel’s distributors.



BT connectivity between instruments and PC is working in most cases but there are still some compatibility problems therefore this functionality is not released yet.
