Triplett AC Line Splitter and GFCI Outlet/Receptacle Tester with 5 Visual Indicators (ET200)

I assume it is accurate on the 1 times but the 10 times is more like 11 or 12 times. Which seems odd. I am pretty sure all they needed to do was loop (or coil) the wire 10 times so that the meter would read 10x the electrons flowing by.

This appears to be substantially the same as several similar units I have or have used. The new thing (to me) is the GFCI testing button. If its not apparent from the picture, the thing that looks like a guard around the GFCI testing button isnt. Im not really sure why its there at all; the button protrudes a few millimeters and takes very little force to depress. So far, Ive successfully tripped a known working in-wall GFCI... and proved to my satisfaction that a GFCI-protected extension cord I bought for cheap from Wal-Mart is probably unsafe / defective(?). (If the GFCI light comes on, probably even for a moment, while connected to a GFCI-protected circuit, its probably time to get a better GFCI. In the case of the extension cord, the GFCI light stayed a bright, solid, ominous red for as long as I cared to hold the button down.) I dont have any out-of-code outlets or appliances Im aware of, so theres a slight question mark about the other functions; it does light the completely correct pattern for all of my known-good outlets, extension cords, etc.

A must have at home!

Great way to check your electric plugs

Used once to check amperage of a sump pump during operation with my Clamp multimeter. Measurement was plausible, most likely correct. Used GFCI tester per instructions provided. Worked well. A convenient way to perform this type of testing if length of the device lets it fit where you need it to be.

So easy to use the graphics right on the plug

Would have liked to have seen how it works-but it didnt work straight out of the package. Piece of junk!! !! Sadly for $8 is not work the time and effort to return it. Avoid.

It has multiple uses and does everything well.

Quality was great came on time as was a gift not sure how it will work but it was wail made

Read instructions, makes it easy to take many reading of 120vac plugs and appliances. All in one tool. Recommended
