Extech MA63 [MA63-NIST] True-RMS AC/DC Clamp Meter 600VAC/DC, 60AAC/DC w/NCV Detector & Variable Frequency Control

The Extech MA63-NIST is an AC/DC 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 MA63 also features resistance, capacitance, frequency, diode and continuity measurements as well as data hold low battery indicator, and auto power off functions. It includes NIST Certification.
