Customer Rating: Summary: Well built and feature packed tool to have Comment: In order to make a current measurement you used to have to break the circuit and run one conductor through your meter's 10A current input and return back to the device from the meter's ground then hope there are no surges over 10A to blow your meter's fuse. With today's advanced amp-clamp meters, and this tool, Safe, Fast, Easy, and Accurate current measurements are posssible.
First, the tool is inserted between your device under test and an AC wall plug.
The tool features 2 "holes" to put your amp clamp into. This eliminates the need to have a split cable with just one wire to put your amp clamp onto. One hole is labled "X1" which has only one wrap of the current carrying wire in it, so your amp clamp will read the actual current used by whatever is plugged into this tool.
The second hole has a trick - Labeled "X10" it features 10 wraps of the current carrying wire and multiplies the meter's reading by 10. By doing this you can just move the decimal point to the LEFT one place and make accurate measurements of very small currents that your amp clamp may not sense accurately otherwise. It's a simple current transformer. Say you are using your clamp on a device that reads 0.1A on the X1 hole. Using the X10 hole your meter could read 0.5 - 1.6 A depending on its rounding numerics. Moving the decimal point one digit left you find what originally was limited by the resolution of your meter to 0.1 A is really 0.05 - 0.16A (again depending on roundoff error you eliminated by using the X10 hole)
There are two other convenient features worth noting other than the X10 current multiplier. Banana jacks are present for Earth, Line, and Neutral to make voltage measurements simultaneously. Also, the somewhat wierd looking "Jack" for the device to plug into is of the "Universal" design found in international hotels and cruise ships which handles most of the USA, Europe, China, Japan, and too many other countries to list. This is the reason the holes on the jack look a little funny and there are 2 ground holes - they accept many plugs equally well. If you are testing an overseas appliance you have an adapter here to the US standard outlet. Combine it with a 2:1 transformer or a variac where needed and you can get 230 volts to run the appliances for countries with 230 VAC voltage standards.
For $11, this adapter can get you out of alot of trouble neatly and extend the low current range of your existing AC amp-clamps. Most people pay $11 just for an overseas adapter. It's a great accessory. Customer Rating: Summary: Handy Tool Comment: This tool makes amperage draw tests extremely fast and easy and very accurate...
