The MG302 is a true RMS multimeter with a built-in insulation resistance tester and 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. 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 4GΩ with 0.001MΩ resolution. The full-function, true RMS digital multimeter includes useful extras, like duty cycle measurements and milliamp readings for analog 4-20mA 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. 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.
