Continuity tester UHV-810

ground

Overview
The UHV-810 Ground Continuity Tester is a portable, highly automated instrument for verifying connectivity and electrical integrity of power equipment and grounding networks in field and workshop tests.

Key features

• Continuous DC output up to 10 A to break contact oxidation films and obtain reliable measurements.
• High anti‑interference performance: last LCD digit stable within ±1 count under severe interference for repeatable readings.
• Long service life: high‑precision resistors reduce temperature influence; military‑grade connectors improve vibration resistance.
• Simple operation: single measurement key; results displayed on a 3 1/2‑digit LCD for intuitive readings.
• Portable design: compact, lightweight panel-and-case integrated structure with seismic resistance for easy transport.
