In electrical safety validation, chassis continuity verification is an essential test to ensure that fault currents can be safely diverted to the protective conductor. A poor connection can pose a significant risk to the user and compromise the equipment’s regulatory compliance.
The ED&D GC-100 Automated Digital Ground Continuity Tester is designed to perform these tests accurately, quickly, and in accordance with international standards, evaluating the integrity of the grounding system in electrical and electronic equipment.
High-current chassis continuity testing
The instrument performs ground continuity tests using high currents, which is essential for detecting contact resistances that would not be evident with low-current tests.
- Selectable test current of 25 A or 30 A
- Compliance with standards such as IEC 60335-1, IEC 62368-1, IEC 61010-1
- Realistic evaluation of the current-carrying capacity of the ground system
In addition, the instrument can run low-current tests simultaneously, expanding the scope of the evaluation.
Automation and ease of operation
The GC-100 incorporates automated functions that simplify test execution:
- Automatic test time selection (1 second or 60 seconds)
- No need for manual timing
- Clear pass or fail indications
This automation reduces operator errors and improves efficiency in production or laboratory environments.
Impedance compensation and accuracy
To ensure reliable results, the instrument has a “zero” function that compensates for test lead resistance before measurement begins.
- Reference adjustment to eliminate conductor impedance
- Greater accuracy in the actual measurement of the equipment under test
- Accuracy of ±2% of full scale
This is especially important in tests where small variations can determine whether or not the equipment meets the standard.
Fault indicators and acceptance criteria
The instrument lets you set resistance thresholds to automatically determine whether the equipment meets safety requirements:
- Standard trip level of 0.1 ohm
- Option to adjust to 0.2 ohm
- Immediate fault indication
These parameters are aligned with typical acceptance criteria in ground continuity testing.
Versatile design and compatibility
The GC-100 is designed to adapt to different environments and connection types:
- Universal input for 120 V and 240 V
- Operating frequency of 50–60 Hz
- Receptacle compatible with multiple plug configurations
This makes it easy to use in different countries or applications without additional adapters.
