The CL360 Electrical Tester is an automatically ranging true root mean squared (TRMS) digital open jaw fork meter that measures AC current via the fork, AC/DC voltage, continuity, and resistance via test leads. It can detect the presence of voltage via the integrated non-contact voltage (NCV) tester. It includes a carrying case, test leads and 2 x AAA batteries. Open Fork Meter with automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy. Tester measures AC current via the clamp, and AC/DC voltage, resistance, and continuity via test leads. Wide jaw for measuring current in cables up to 3/0 sizes; accommodates cables of diameter up to 0.58-Inch (1.5 cm). Non-contact voltage tester integrated into the jaw. Includes a carrying case, test leads and 2 x AAA batteries. Jaw and Housing: CATIV 600V/CATIII 1000V; Electrical: CATIII 600V/CATII 1000V; Class 2, Double Insulation. Backlit display for clear readings. Powers off automatically after 15 minutes of non-use to conserve battery life. Rugged Klein TOUGH METER is built to withstand a 9.9-Foot (3m) drop. Low battery indicator and easily accessible battery compartment.
