GENERAL SPECIFICATIONS
Klein Tools MM720 is an automatically ranging true root mean square
(TRMS) digital multimeter that measures AC/DC voltage, AC/DC current,
and resistance. It can also measure temperature, capacitance, frequency,
duty-cycle, test diodes and continuity. It features a high visibility, reverse
contrast LCD display with an optical sensor to automatically optimize
viewability in dark or bright ambient lighting.
