True RMS Clamp Meter Digital Multimeter DC AC Current Volt Amp Ohm Diode APPLink
The most convenient way without peeling the cord is clamp on an AC Line Splitter. Capacitance: 6nF-60mF. Jaw: open 26 mm to close the conductor. Diode Test. The curve graph w/ timing will show you the changes of amp volt flow more visually.
