•Model 480172 AC Line Splitter

•Model 40130 Voltage Detector

•Set of 1000V Category III test leads

•Type K thermocouple temperature probe

•Model CA900 Carrying Case

•Operation Manuals for the Models 38389 and TK32

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
