The T6-600 with FieldSense technology lets you measure AC voltage and AC current with or without test leads. Its compact design lets you access tight spaces that were previously not possible. With FieldSense selected, slide the open jaw around a cable and measure up to 200 A and 600 V without breaking the circuit. The backlight display makes the values easy to read. Rated to 600V CAT III and with resistance measuring up to 1000 Ω, the T6 is the perfect front-line tool for basic troubleshooting. Be Safer: Measure voltage to 600V through the open fork, without test leads.
