GENERAL SPECIFICATIONS
Klein Tools CL490 is an auto-ranging true root mean square (TRMS)
digital clamp meter that measures AC/DC current via the clamp, AC/DC
voltage, DC microamps, resistance, continuity, frequency, capacitance,
tests diodes via test-leads, and temperature via a thermocouple probe.
It features high visibility, reverse contrast transflective LCD main and
secondary displays that optimize viewability in dark or bright ambient
environments.
