GENERAL SPECIFICATIONS
Klein Tools CL440 is an automatically ranging true root mean
square (TRMS) digital clamp meter that measures AC current and
inrush via the clamp, AC/DC voltage, DC microamps, resistance,
continuity, frequency, capacitance, and tests diodes via test-leads, and
temperature via a thermocouple probe.
