Review on BTMETER BT-570CAPP Bluetooth AC DC Clamp Multimeter Amp Meter with Temperature Testing, Auto-ranging for Current, Voltage, Resistance, Capacitance, Continuity, Amperage, Volt, Ohm Clamp-on Ammeter by Michael Mendoza

Very happy with this multimeter, I need a DC jumper clamp and it ticks the bill. The app is pretty good when it works, it has to be closed and reopened when it loses connection due to range. Be sure to use the relative function as it sometimes draws phantom power. When you first switch it to DC mode, press Relative and it will reset to zero. You can see in the picture that it reads 2.5 amps when there is absolutely no load. Press the rel button to fix it.
