Most ATORCH smart meters use the Tuya or Smart Life app. Enable Bluetooth and GPS on your smartphone, put the device in pairing mode (often by long-pressing a button until the WiFi LED flashes), and add the device within the app.
Mobile apps like 'E-test', 'Tuya', or 'Smart Life' can be found in the Apple App Store or Google Play. PC software and specific APKs are typically available at the official website, www.atorch.cn.
Some USB testers, especially those measuring PD protocols, require a load (like a phone) to be connected to the output port before the charger initiates power output and the screen lights up.
Reset methods vary by model, but commonly involve a long press of the function key, or specific shortcuts like double-clicking or triple-clicking the main button while on the capacity screen.
