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 Jorge Kumar

The column wheel feels rough right out of the box. I have to rock it back and forth to get the correct reading. Bluetooth is properly connected. First page min max etc works fine. The dates are ok. For my use, a display speed of 0.1s would make sense. I have graphic problems. It tends to stay on a certain scale which is totally unsuitable for DC measurement. He will return whenever he wants. The graphics seem to outperform all other modes. The "manual" mentions that help is available in the app. Not on mine.
