Service Ground Test Set (900)
$1,936.00
TESCO’s Service Ground Test Set (Catalog No. 900) is engineered to confirm the condition of a service ground connection with clarity and precision. Designed around a suppressed-zero voltmeter and internal shunt, this compact instrument identifies resistance in the ground path by displaying any resulting voltage drop. It also doubles as a diagnostic tool for potential transformers, placing a measurable burden on the secondary to detect performance issues. Whether verifying a meter installation or investigating transformer functionality, the 900 offers dependable accuracy in the field.
Description
Features
- Verifies Ground Integrity: Quickly identifies resistance in secondary service ground connections.
