Klein® CL320 clamp meter is an automatically ranging true root mean square (TRMS) digital clamp meter that measures AC current and NCVT via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance and tests diodes via test-leads and temperature via a thermocouple probe. Features include auto range to improve efficiency and speed when making measurements, diode test to troubleshoot malfunctioning diodes, max/min to understand the variability from average of an electrical property being measured and DC microamps measurements when working with flame sensors.
