VOLT METER/CLAMP METER CM-9940 .
Measure up to 600 A AC / DC

This Voltmeter can measure both direct and alternating current.
The CM-9940 Voltmeter also has basic functions of direct and alternating current, resistance, frequency, transit and diodes. The voltmeter is a very useful instrument for the technical service of domestic appliances due to its small size (only 30mm). The CM-9940 voltmeter has overload protection for all functions and ranges.
