This multimeter works exactly as I expected. Installation was easy (I plugged it into the socket on my Trotec Speedy500 laser). The split core transformer was much better. I'm not sure what the other reviewers meant when they said it only showed current readings up to 5A. My device displayed instantaneous current values over 7 A (at 120 V). If values over 1000 are stored in the Wh field, it is automatically switched to kWh. Says it can store information up to 999.9 kWh.
