AC Line Splitter
1937
-
Peaceful Thriving Enterprise Co Ltd
The AC line splitter is a helpful testing device for electrician. Electrician can measure the current with clamp meter through the X1 and X10 measuring rings. X1 is 1:1 measurement, and X10 is ten times (1:10) of the actual current, which is helpful for small current measurement. This device also combines the function of socket tester and GFCI tester, which means electrician can use this tester to test socket and load at the same time.
