Milliohm Meter - Electronic Specialties

The Electronic Specialties Model 560 Milliohm Meter is a professional-grade diagnostic tool engineered for precise low resistance measurements in both automotive and industrial applications. It is an essential instrument for technicians working with electric vehicles (EV) and hybrid systems, ensuring the integrity and efficiency of critical electrical components.

Key Features

• High-Resolution Resistance Measurement: Provides accurate low resistance readings with a resolution of 0.1 milliohm (0.0001 ohm).
• Kelvin Test Leads: Includes Kelvin test leads for four-wire measurements, which helps minimize lead resistance influence and ensures precise readings.
• Comprehensive DVOM Functionality: Functions as a full Digital Volt-Ohm Meter (DVOM), capable of measuring volts, amps, ohms, capacitance, continuity, and performing diode testing.
• Safety and Data Capture: CAT III 1000V approved, offering safety for high-voltage environments, and features Min/Max capture to record high and low readings.
• Complete Kit: Comes with a durable blow-molded case and six AA batteries for immediate operation and protected storage.

Applications

The Model 560 is critical for diagnosing performance issues in EV and hybrid three-phase motors by allowing technicians to check stator windings for inconsistent or out-of-range resistance values. This diagnostic procedure is vital for ensuring the integrity, efficiency, and reliability of the electric motor’s winding. In three-phase stators, all phases should exhibit nearly identical resistance values; the 560 assists in identifying discrepancies that can lead to drivability problems and other common electric motor failures.
