Full 20A Current Capacity
All 120V power tools that rates up to 20A can be tested.

Low Maintenance
The Model 350 SHORT STOP offers solid state electronic circuits, dependable neon displays, and components recognized by Underwriters Laboratories.

Line to Line Short
Tester activates a Short-Line lamp and locks out all other circuits if line to line impedance of item under test is three ohms or less. This protects the equipment under test and the tester’s internal circuits.

Line to Case Short
Tester activates a Short-Case lamp if the line to case fault current exceeds 10 milliamps.

Tests quality of ground wire
The quality and continuity of the ground circuit is measured. Poor quality ground connections are rejected.

Verifies tool performance
Dual-scale ammeter reads the current drawn by tool. This helps identify defective bearings, gear trains, shorted coils or poor brush contact.

Tests extension cords
A built-in extension cord test checks continuity and ground wire resistance.
Direct Reading Leakage Meter
Displays actual leakage current with good, marginal and danger levels clearly shown.

Provides a built-in reference for self-verification

Dual Scale Ammeter
Current draw by the product is displayed on a dual scale ammeter. The upper scale reads 0-20 amperes, the lower scale reads 0-5 amperes. This helps identify defective bearings, gear trains, shorted coils or poor brush contact.

No Dangerous High Voltage
All tests are performed at normal line voltage. Repeated high voltage testing degrades a tool’s insulation and presents an employee hazard.

User Friendly
The Number 1 to 5 test buttons and the PASS and FAIL lamps make it so easy that employees are encouraged to check their tools before each use.
