Current Clamp and Line Splitter
Line Splitter
The supplied Line Splitter provides a means to cleanly “open” a standard 120V line cord in
order to make clamp type current measurements. When connected between the 120V AC
wall outlet and the device under test, the Current Clamp can then be clamped on one of
the two test openings in the Splitter. One opening provides a one-to-one current reading
and the other provides a times-ten (X10) reading so that small current will display with
better resolution on the clamp meter.

Line Splitter Operation:
Current Measurements
1. Plug the AC Line Splitter into the 120V receptacle
2. Plug the line cord from the load into the AC Line Splitter socket
3. Close the Clamp-on jaws around either the X1 or X10 arm of the AC Line Splitter
4. If the X1 position is used, read the current directly on the meter
5. If the X10 position is used, divide the meter reading by 10 to obtain the actual
current
Voltage Measurements
1. Plug the AC Line Splitter into the 120V receptacle
2. Insert the multimeter test leads into the two Voltage Test jacks
3. Read the voltage on the multimeter
