A grounding resistance meter that can measure grounding resistance from Type A to Type D.
**Features** - Ground resistance meter compliant with JIS standards - Wide measurement range Accurately measures ground resistance from Type A to Type D grounding work. Additionally, measurements can be taken up to 115% of the measurement range. - More stable measurements Easily check the grounding condition of auxiliary grounding rods for greater accuracy. Furthermore, the measurement frequency can be switched to prevent the effects of harmonic ground currents. - Simple measurement function Switching between normal and simple measurement modes can be done with a single touch of a switch. - Overvoltage protection and warning function During simple measurements with commercial power sources, common miswiring is safely warned by an alarm buzzer and overvoltage protection (AC 250V/1 minute). - Resistant to mud and dirt Enhanced dust resistance for measurement switches and dials, improving durability. - More convenient accessories Tangles of measurement cables can be easily organized with a cable winder.
