Extech MA61: 60A True RMS AC Clamp Meter + NCV

Compact Clamp Meter with Non-Contact Voltage Detector and Variable Frequency Control


The MA61 is an AC current clamp with NCV voltage detector and full overload protection. Manual ranging clamp meter with three Current ranges and AC/DC voltage to 600V. The 6000mA range allows for low current measurements that may be used in the automotive industry. Unique VFC (variable frequency control) mode helps troubleshoot and diagnose HVAC applications that are variable frequency driven. The MA61 also features resistance, capacitance, frequency, diode and continuity measurements as well as data hold low battery indicator, and auto power off functions. Complete with test leads, carrying case, and two AAA batteries.
