We were duscussing an AC line splitter, for using clamp-on meters.
The one for sale was
It has two holes in in it, apparently X1 and X10.
The instructions
- Close the Clamp-on jaws around either the X1 or X10 arm of the AC Line Splitter
- If the X1 position is used, read the current directly on the meter
- If the X10 position is used, divide the meter reading by 10 to obtain the actual current
How do they do that? I can see using a resistor to make the reading lower than fact (though this would interfere with the operatoin of the device to be measured), but how do they make it higher than fact. (And doesn't that interfere too?)
