Fluke FLK-SMFT-1000/LITE, Multifunction Tester

The SMFT-1000/LITE is a field-tested multifunction tester engineered for solar-PV installations and electrical system checks. It combines safety verification, performance measurement, and diagnostic capabilities into a single handheld device. It is designed for solar contractors, installers, inspection teams, and maintenance engineers requiring a reliable, portable instrument for documenting compliance and system health without carrying multiple devices.

Salient Features and Benefits of Choosing the Fluke SMFT-1000 Multifunction Tester

The SMFT-1000/LITE covers a broad range of test functions that make it versatile for solar-PV and electrical work:

• Protective earth/conductor resistance (RLo) measurement.
• Open-circuit voltage (Voc) and polarity check for PV modules/strings (up to 1000 V DC).
• Short-circuit or operational current (Isc) measurement (up to 20 A DC).
• Insulation resistance (Rins) testing across a wide resistance range.
• Automatic test sequences for safety checks and compliance verification.
• Data storage and export for auditing, reporting, or maintenance logs.

Designed for Convenience, Safety & Compliance

SMFT-1000/LITE is built with real-world use in mind. It carries a CAT III 1000 V safety rating under IEC 61010‑2, ensuring safe operation during testing of high DC voltages typical of solar installations. Its onboard interface, with clear screen guidance and an option for the “Keep-the-Leads” function, streamlines testing workflows. This reduces setup time and minimises human error, a critical advantage when handling high-voltage systems or performing multiple tests across many PV strings.

Versatility in Applications

This model fits well in:

• Commissioning new solar PV installations tests modules/strings for correct wiring, insulation, Voc/Isc, and earth continuity before activation.
• Periodic maintenance and inspection check insulation integrity, grounding, and module string output to spot degradation or faults over time.
• Troubleshooting faulty arrays uses voltage, current, insulation, and polarity tests to identify defective modules, wiring issues, or ground faults.
• Compliance verification for reports required under industry or regulatory standards.
