The MA63 is an AC/DC clamp meter with NCV voltage detector and full overload protection. Manual clamp meter with three current ranges and AC/DC voltage up to 600V. The 6000mA range allows the measurement of low currents that can be used in the automotive industry. The unique VFC (Variable Frequency Control) operating mode helps troubleshoot and diagnose HVAC applications that operate at variable frequency. The MA63 can also measure resistance, capacitance, frequency, diodes and continuity and has a reading memory, low battery indicator and auto power off function. Includes test leads, carrying case and two AAA batteries.
