Klein Tools CL380 Electrical Tester is an automatically ranging true root mean squared (TRMS) digital clamp meter that measures AC/DC current via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads, and temperature via a thermocouple probe. It includes a non-contact voltage tester integrated into the clamp, and features a high visibility, reverse contrast LCD display that optimizes viewability both in dark or bright ambient lighting.

• Warnings
• Read, understand, and follow all instructions, cautions and warnings attached to and/or packed with all test and measurement devices before each use
• Before each use, verify meter operation by measuring a known voltage or current
• Never use the meter on a circuit with voltages that exceed the category based rating of this meter
• Always adhere to local and national safety codes. Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed
• Usage of this meter in any way other than that specified by the manufacturer can impair safe operation, resulting in severe injury or death
