Press five times to display the voltage and current of channel C, press once more to display the energy and power (pay attention to ABC on the display screen).

Press the seventh time to re-display the voltage, current, energy, and power of channel A, and continue in this cycle.

Frequently Asked Questions (Q&A)

Q: Why is channel current and power on displayed as 0 after viewing the product interface?

A: You can only sense the current by passing the line of the device you want to measure through the current transformer, after which the APP will display real-time current and power values.

Q: I changed the setting item to change the value of other parameters. Why does my product interface seem to be stuck?

A: This is caused by network latency or lag. Please log out of the application and re-enter.

Q: How to clear the electricity data of smart meters?

A: Please go to the smart meter APP interface, click the "..." menu, slide to the bottom right corner, and click delete device.

Q: Is the external temperature probe included with the standard package?

A: The device supports a temperature detection range from -40°C to +100°C; however, the external temperature probe is not included as standard and must be ordered separately.

Q: What is the standard current transformer aperture size and can it be customized?

A: The standard Current Transformer Aperture is 10MM. Customizable large calibers are available upon request to accommodate higher diameter electrical lines.

Q: Can this monitor both household consumption and solar photovoltaic generation?

A: Yes, installed as a master monitor in your electrical distribution box, it tracks comprehensive household power usage and monitors generation from solar photovoltaic systems.
