The Clamp on Tester measures current and voltage values using the connected current transformers and test leads. From this, the active, apparent and reactive power are determined and transmitted to the measuring platform every second via Wi-Fi. The data is then filed historically on the Clamp on Tester, processed graphically and can be analysed or exported. The measurement with the Clamp on Tester is carried out using Rogowski coils or folding current transformers.

Alternatively (if no internet connection is available), the data can be recorded in the built-in 32 GB flash memory in the form of a CSV file for further processing at a later date. An SD card adaptor is also available as an accessory, which means that the recording duration is more than one year, even when recording to the second. It is also possible to send the CSV files periodically by e-mail, upload them to a server via FTP or transfer them to the measurement platform once the measurement has been completed. Interaction with the Clamp on Tester is mainly via Wi-Fi and web browser or via app (BLE).

Power is supplied and measured via magnetic measuring tips and connection terminals or probes. The Clamp on Tester can be connected into any main and sub-distribution board as well as into devices and systems - the power supply does not have to be interrupted. Managing the power supply is the top priority. Without measuring consumption and recording instrumental values such as current, voltage, frequency and power, it is virtually impossible to improve efficiency. The Clamp on Tester makes it possible to monitor the entire energy consumption and helps to reduce energy costs.
