The state-of-the-art Clamp on Tester enables precise and comprehensive measurements in the areas of current, voltage, frequency, power, energy flicker and harmonics. It has been specially developed to provide reliable data both in industrial applications and when analyzing photovoltaic or inverter systems.
Simultaneous monitoring of all three phases and the neutral conductor provides a complete picture of the electrical system. The efficiency measurement of inverters allows a detailed analysis of the energy conversion, while the grid signal monitoring continuously detects deviations and faults. This Clamp on Tester is therefore an indispensable tool for professional energy analyses.
Thanks to modern communication interfaces such as Wifi, the Clamp on Tester can be easily integrated into existing systems and enables wireless analysis of measurement data. The integrated logger function and the memory reliably save all relevant data for later analysis.
An integrated oscilloscope function allows the visual display of signal curves, including inrush currents, and thus supports the analysis of transient phenomena. The 7.8-inch touch display ensures intuitive operation and a clear presentation of all measured values, diagrams and analysis functions. The Clamp on Tester fulfils the requirements of IEC 61000-4-30 Class A and thus guarantees standard-compliant analysis of the power quality parameters.
This Clamp on Tester combines precision, versatility and modern user-friendliness and is ideal for energy analyses, fault diagnostics and efficiency tests in complex electrical systems.
