Extech MG300-MTK Motor and Drive Troubleshooting Kit

The MG300 is a True RMS multimeter that incorporates a digital insulation resistance tester (or megohmmeter) with four different test voltages for measuring resistance up to 4 GΩ with 0.001 MΩ resolution, and duty cycle measurements and milliamp readings for analog 4-20 mA current loops in industrial analog process controls. The MG300 also has built-in wireless data recording for safer troubleshooting and maintenance on moving equipment, one-person operation of remote safety switches, and the ability to monitor real-time readings on a laptop or computer screen from safe distances — up to 30 feet away — to detect intermittent anomalies.

The MA430T is a compact 400 amp 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 350 MCM. 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: backlit LCD display, data hold, auto power off and low battery indication.
