Insulation Tester/Multimeter with Wireless PC Interface Designed for users outside of North America because of its 433 MHz wireless transmitter frequency, the MG302 is a true RMS multimeter with built-in insulation resistance tester with the added safety of wireless data streaming for remote monitoring and data recording. By adding insulation testing capabilities to this CAT IV-rated digital multimeter, electrical troubleshooters will always be equipped for insulation testing, helping to make it a more routine part of predictive maintenance with faster troubleshooting and repairs without the need for additional tools. MG302 Features Overview The rugged and waterproof (IP67-rated) combination meter includes a digital insulation resistance tester (or megohmmeter) with four different test voltages for measuring resistance up to 4 GΩ with 0.001 MΩ resolution. The full-function, true RMS digital multimeter includes useful extras, like duty cycle measurements and milliamp readings for analog 4-20 mA current loops in industrial analog process controls. The MG302 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. Applications Insulation testers can be used to test motor, transformer windings, instruments, and appliances, check for moisture in wire and cable assemblies, safely evaluate a new wiring installation, and check for carbon tracking in breakers, relays, and switches. Extech Insulation Testers offer high sensitivity to assure reliable monitoring of low resistance motor windings. What's in the Box The MG302 comes with a remote USB receiver, Windows compatible software, test leads with alligator clips, Type K bead wire temperature probe with adapter, carrying case, six AA batteries, and user manual. The MG302 is available with NIST-traceable certification (model MG302-NIST).
