Rod-L M30 Ground Continuity Test Instrument w/ S002-05 Probe

The Rod-L M30 is a ground continuity test instrument that verifies the integrity of grounding paths in electrical systems. It measures total resistance between a device's chassis and AC power-in cord ground, ensuring the path can safely shunt leakage currents and transient voltage spikes to earth ground. The M30 delivers 30 amperes of test current across a 0 to 0.15 Ohms measurement range, with ±5% full-scale accuracy.

Designed for laboratory and production environments, it meets BSI, VDE, and IEC standards and includes the S002-05 Eclipse Magnetic Chassis Ground Probe for convenient contact-based testing.

Typical Applications The M30 evaluates ground continuity on devices before certification and production release. A test unit plugs into the front panel receptacle, applying a precisely regulated test current while displaying total ground circuit resistance. User-preset rear panel controls set resistance limits; detected faults trigger immediate shutdown and alarm notification.

Compatibility & Integration Complies with BSI, VDE, and IEC safety standards. Instrument cabinet and front panel must be grounded via the included 3-conductor power cord. The mains socket must provide a functioning safety ground. High voltage mating plug and cap are factory-installed on the rear panel HV OUT/INTERFACE connector.
