Review on 🔧 BTMETER BT-570S-APP Digital Clamp Multimeter with Bluetooth, 6000 Counts TRMS Clamp-on Ammeter Auto Ranging Voltage Tester AC DC Volt Amp Ohm NCV Temperature Capacitance Measurement by Michael Welborn

The ability to measure DC clamps was a real draw for me. Unfortunately, it wasn't great in use. The high offset was annoying but the guide tells you how to work around it but the offset drift was still there. The erratic operation of the switch was the most worrisome; I had to shake it from time to time for it to display readings correctly. The beep on my device was very quiet; this does not make sense at higher noise levels. The Bluetooth interface might help, I sent my meter back before trying it. Maybe I was just unlucky and you could get a good one.
