Check the input connections ( IN terminals) with a multimeter to verify that 230V AC power is actively reaching the device.

Press and hold the DOWN button for more than 12 seconds to revert all options to default settings. Parameter Configuration Table (Step-by-Step Manual)

A: Yes, it uses a shunt resistor (Class 1 accuracy, +/- 1%). It is accurate enough for billing estimation but not for revenue-grade metering.

Note: The device will automatically save your settings and exit back to the real-time monitoring home screen if no buttons are pressed for 15 seconds. Operational Mechanics: How It Protects 1. The Power-On Delay (A1)

To adjust the over/under voltage trip points without the app, follow this manual procedure:
