Ever wonder what is your household appliances’ power consumption? Is your television consuming too much power or it is time to replace a new one with power saving? Is your desktop computer’s power supply giving enough juices to your computer or it is overloaded? The answer will be unknown unless you look into the real Watt value of the power consumption.
I bought this little gadget few years back for RM85 from the Lowyat forum. It is now still selling at about the same price I bought. Have been using this to measure my electronic projects‘ power consumption and to check the power consumption of my household appliances to see they are still working in good condition.
It is not 100% accurate I believe but it gives you an idea how much power you are using. The user manual claims it has accuracy of +- 1%. It also claims that the product is protected by the “Chinese Patent” (Patent No. ZL2006200165630). I think it means the “China Patent”?
Using this Wattmeter is super simple. Simply plug-in the appliance you want to measure to the Wattmeter and connect the Wattmeter to an outer power supply. Power on the outer power supply and start using the appliance. Press menu or up/down button on the Wattmeter to get readings in different units.
Main Features Of The Wattmeter
- Measure supply voltage in real-time.
- Measure appliances power usage in real-time (0~3000W).
- Show accumulated power consumption (0~9999kWh).
- Calculate the cost of energy according to the preset price of energy (0~$9999); You will first need to set the unit price.
- Operation condition monitor: The indicator light will flicker when the real-time ratio of operation condition reaches its alarm point.
- Show the operation time of appliances (0~24h~9999d). In single time mode or accumulated time mode.
What Do You Get In The Box
- A Multifunctional Mini Ammeter (Wattmeter).
- A user manual.
