GENERAL SPECIFICATIONS
Klein Tools CL312 is an automatically ranging true root mean square
(TRMS) digital clamp meter that 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.
