Power Meter
1. Screen
2. "SET/CLR" Button
Used to erase the accumulative total energy consumption
or the accumulative power-on time data from memory.
I. INTRODUCTION
This Power Meter can be used to measure the average power and energy consumption of electrical appliance and can be
used for energy saving evaluation. It is easy to use and is an ideal test tool for home and industrial enterprises.
To use the Power Meter, plug the instrument into a standard AC outlet. Then insert the plug of the appliance to be
monitored into the socket of the instrument.
3. Socket
Used to connect the electrical appliance to be monitored.
4. "DISP" Button
Used to cycle through different data.

I I. DISPLAY
After the Power Meter is plugged into ac outlet, its screen will show the dynamic average power of the appliance
connected. You can press the "DISP" button repeatedly to cycle through different data. See the following table:
DISPLAY ITEM DESCRIPTION
Default item, the display shows the dynamic average
power of the appliance being monitored.
Press the "DISP" button once to display the
accumulative total energy consumption.
Press the "DISP" button a second time to display the current
presently consumed by the appliance being monitored.
Press the "DISP" button a third time to display the
voltage of the power supply.
Press the "DISP" button a fourth time to display the
frequency of the voltage of the power supply.
Press the "DISP" button a fifth time to display the
accumulative power-on time of the Power Meter.
III. OPERATING INSTRUCTION
DATA ERASURE
When the display shows the accumulative total energy consumption or the Power Meter’s accumulative
power-on time, you can press and hold down the "SET/CLR" button for more than 5 secs to erase this
presently displayed value from memory.
DISPLAY AND READ OPERATION
Pressing the "DISP" button repeatedly will cycle through the following recorded data on the screen:
dynamic average power (default) of the appliance, the accumulative total energy consumption, the current
presently consumed by the appliance, the voltage of the power supply, the frequency of the voltage of the
power supply, and the accumulative power-on time of the Power Meter.
