Micro Wireless Electricity Monitor is a device that can monitor the power consumption of household appliances and display the corresponding power consumption and cost.
This manual covers safety and care guidelines, explains how the monitor works using current‑transformer sensing, and describes the display and transmitter features. It also details the wireless transmission at 433 MHz, the 30‑metre range, and the accuracy of about ±10 % for measuring power consumption.
The getting‑started section walks you through unpacking, inserting two AAA batteries, synchronising the transmitter with the display, and using the SET and RESET keys to adjust cost settings, switch display modes, and clear accumulated data. Warranty, compliance, and returns information are provided at the end of the document.
