Electrical testing instruments get software upgrade

Louise Smyth

The upgrade enables visualization, data management, and audit-proof documentation of all test events across devices. For the first time, measurement and test data from different testers and multimeters can be collated in one inspection. Objects and places are assigned via drag and drop. Therefore, even complex procedures become very easy, for instance assigning datasets to other locations such as lots, buildings, levels, and rooms. Individual test structures can be directly uploaded to the test instrument. Control options also include practical features such as a push/print function to further simplify the transmission of measured values with all relevant characteristics. The business starter version installed by default in all PROFITEST MASTER instruments can be upgraded be at any time as needed. Additional Business versions are available, as well as network-enabled enterprise versions. This expands the capabilities of the CAT IV devices.


The series is designed for testing and measuring tasks in all AC and three-phase networks with voltages from 65 V to 500 V and frequencies from 15.4 Hz to 420 Hz. The systems support all tests according to DIN VDE 0100-600 / DIN VDE 0105-100 to check the effectiveness of protection measures in electrical installations in private homes, commercial buildings, and industrial facilities. On top of basic standard tests, PROFITEST MASTER offers numerous additional measuring functions and meets the requirements for acceptance tests and periodic inspections in fixed electrical installations. The devices' ergonomic design and user-friendly operation simplify the selection and setup of test sequences. The current measuring method and values are always clearly shown on the integrated illuminated display.
