Fluke 1662 Multifunction Testers

Part #:

The Fluke 1662 Multifunction Tester is engineered for comprehensive electrical diagnostics, offering precision and reliability in a single handheld instrument. It accurately tests both voltage and frequency while checking wiring polarity to quickly identify any broken neutral wires. Additionally, it measures insulation resistance as well as loop and line resistance, ensuring critical parameters are within safe operating levels. The tester also performs continuity checks on motor windings and uniquely calculates prospective earth fault current (PEFC/IK) and prospective short-circuit current (PSC/IK), making it an essential tool for maintaining electrical safety and performance across a wide range of applications.
