basic information

<About the Insulation Resistance Monitoring Device> Traditionally, when measuring the insulation resistance values of electric motors and similar equipment, a megohmmeter is used for manual measurements. However, depending on the equipment and the number of units, tasks such as wiring removal for measurement preparation can take an enormous amount of time and labor. Therefore, the "Insulation Resistance Monitoring Device" has been developed to automate the insulation resistance monitoring process by unitizing it.
