    Nice build, seems sturdy when handled. Strong springs. Needs a screwdriver to open the 9V battery compartment, though.

    Very good! I tested 12v dc and 230v ac. wotking fine.

    this AC current probe is an entry level model, but it gives you the opportunity to display on the oscilloscope the waveform of the ac current in your load keepeing everything insulated from the power supply. I made a quick check with a resistor load connected to the output of a 50Hz transformer and the result of the measurement is shown in the photo. As soon as I can I will check the precision of the displayed signal and I will try with higher frequencies and different kind of loads, but it looks that the probe works as promised. The clamp spring is a little bit strong, the overall construction is solid even if it feels like you have a toy in your hand. Anyway it ias a very good valur for money compared to the price of products of other brands if you are a student or an hobbist. Questa sonda di corrente alternata è un modello base, ma offre l'opportunità di mostrare sull'oscilloscopio la forma d'onda della corrente ac nel tuo carico, mantenendo tutto l'isolamento dall'alimentazione. Ho fatto un controllo veloce con un carico resistivo collegato all'uscita di un trasformatore a 50Hz e il risultato della misura è mostrato nella foto. Appena possibile posso controllare la precisione del segnale visualizzato e cercherò con frequenze più alte e diversi tipi di carico, ma sembra che la sonda funzioni come promesso. La molla del morsetto è un po 'forte, la costruzione complessiva è solida anche se sembra di avere un giocattolo in mano. Comunque, la sonda ha un rapporto prezzo prestazioni molto buono rispetto a prodotti di altre marche se sei uno studente o un hobbista.

    The unit works to specification. Bandwidth was measured with ~80mApp and is exactly the specified 20KHz. The zero-ing function was surprisingly precise. A great value for measuring power line inrush surges, but has insufficient bandwidth for full detail of SMPS pulses or ESD transients. Types with much higher bandwidth come at much higher cost. Attached shows square wave response and noise bands at 2KHz and 10mA/div.

    Everything's working just fine.

    Good value for the money. Gives comparable results to much more expensive current clamps in its rated range. Have read other reviews on this current clamp that complain about unwanted oscillations but I can't measure any unwanted oscillations on either of my two units

    All good. Great price, fast shipping from CZ. The only drawback, that it need's 9V battery.

    Tested on comparison with E3N by Chauvin Arnoux on Hantek DSO 5102P - no difference at all. Great performance for reasonable money
