| 摘要 |
The invention relates to a clip-on ammeter comprising a current detection unit (1), an evaluation unit (2) and a USB interface (3). The current detection unit (1) makes it possible to detect current values and make the current values available as measured values; the evaluation unit (2) includes an analog to digital converter and is connected to the current detection unit (1); the evaluation unit (2) allows the measured values to be transmitted in a processable manner as USB-compatible digital data to the USB interface (3); and the USB interface (3) is connected to the evaluation unit (2) and allows the USB-compatible data to be made available in a transmissible manner for further processing. The evaluation unit (2) can be energized using the USB interface (3). The clip-on ammeter further comprises a voltage transformer (9) that can be energized by the USB interface (3), the voltage transformer (9) making it possible to supply a stabilized voltage as reference voltage for the current detection unit. |
