This Tool Set includes a Digital Clamp Meter (Cat. No. CL600) and a Mini Ratchet Set (Cat. No. 65200). The CL600 Electrical Tester is an automatically ranging true mean squared (TRMS) digital clamp meter measures AC current via the clamp, and measures AC/DC voltage, resistance, continuity, and tests diodes via test-leads. Exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters loaded with innovative, time-saving features. The Slim-Profile Mini Ratchet Set is the perfect answer for fastening in small, tight spaces. The 72-tooth, low-profile gear head only needs 5-Degrees of sweep allowing professionals to fasten in spots other drivers just won't fit. Handle is designed with a finger loop for control and convenience, and is made of high-strength Chromium-Vanadium steel for increased torque and long tool life. The 1/4-Inch dual-drive head has integrated 5/16 and 1/4-Inch nut drivers. This set also comes with a versatile set of bits including #1 and #2 Phillips driver bits, 3/16 and 1/4-Inch slotted driver bits, and an 1/4-Inch drive socket adapter. So, there's no need to go back to the toolbox.
