Extech Instruments 480172 AC Line Splitter User's Manual

AC Line Splitter ‐ Model 480172
Operation
Specifications
The Line Splitter provides a means to cleanly “open” a standard 120V AC line cord in order to
make clamp type current measurements. When connected between the 120V AC wall outlet
and the device under test, a clamp meter can then be clamped around 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 a
clamp meter.

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
