ENGLISH
Klein Tools MM450 is an auto-ranging, true root mean square (TRMS)
multimeter that measures AC/DC voltage, AC/DC current, and resistance. It
can also measure temperature, capacitance, frequency, duty-cycle, and test
diodes and continuity. It features lead alert protection and a high visibility,
reverse contrast LCD display with an optical sensor to automatically
optimize viewability in dark or bright ambient lighting.
