Klein Tools CL312 Electrical Tester is an automatically ranging true root mean square (TRMS) digital clamp meter. It measures AC current 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.
