MA430T – 400A True RMS AC Clamp Meter + NCV

The MA430T is a compact 400A AC clamp meter that enables users to take measurements in tight spaces while offering an ample 1.2-inch (30mm) jaw opening to accommodate conductors up to 350MCM. The MA430T also features: True RMS for better accuracy when measuring distorted waveforms; a large four-digit readout and illuminated display that enhances viewing in poorly lit work areas; and a thumb-dial selector that facilitates convenient, one-handed operation. The MA430T’s multimeter functions include: AC/DC voltage, resistance, diode, and continuity. Also built into the MA430T is the non-contact voltage (NCV) detector. Eliminating the need for a separate tester, the NCV detector uses a red LED to alert users to the presence of voltage on live wires. Additional features include a backlit LCD display, data hold, auto power off, and low battery indication. Complete with test leads, 9-volt battery, soft carrying case, and user manual.
