EXTECH 380363 Digital High Voltage Insulation Tester measures Insulation Resistance to 60GΩ with test voltages of 500V, 1000V, 2500V, and 5000V.Comes with test leads, eight C batteries, 120V AC adaptor, heavy duty carrying case, and user manual.

The Model 380363 provides three test ranges plus continuity and AC/DC voltage measurement. Manual datalogging stores up to 9 data sets

Auto Power Off To conserve battery life, the meter will automatically turn off after 15 minutes of non-use. To turn the meter back on, turn the rotary switch to OFF, then to the desired function. Analog Bar Graph The analog bar graph displays resistance on a logarithmic scale and voltage on a linear scale. The value always tracks the main display.

Using the Extech 380363  LOCK Function to measure resistance The Lock function can be used to make several resistance measurements in succession without the need to push and hold the TEST key for each measurement. Note: The meter cannot indicate if the circuit is live in this mode. Ensure that the circuit is de-energized before connecting the test leads or the fuse may blow.

Additional Features

Polarization Index measurement (PI), Dielectric Absorption Ratio measurement (DAR), AC/DC Voltage measurement to 600V with Min/Max, Peak and Relative functions, and 1 to 15 minute timer function for IR measurements.

Application and use of insulation testers:

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.

Designed for users outside of North America because of its 433 MHz wireless transmitter frequency, the Extech 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.
