1.Input Voltage：AC 100V-250V.The input Voltage is the same as the testing Voltage.

2. It could test not only the lighting products but also any other electric appliance among 100V-250V

3．Maximum testing Wattage ：300W

4．Testing parameters：Voltage，Wattage，Power Factor，Annual power consumption（calculated based on 10 hrs/day）.

5. Four switches control the four lamps separately. Turn off the other three lamps if you want to test parameter of one lamp. Turn on the four lamps at the same time, the parameter will show the grand total of 4 lamps.

6. With different base:E14，B15，B22，GU10，G9,it could test different lamps with different base.

7.With an additional power cord socket in the back of the power meter, it could connect many display power meters at the same time.

8. With fuse inside the power socket, it could protect load short circuit。

9.The background of the tester could be designed according to client’s requirements ,also could be put the LOGO of client on the power meter
