Kusam Meco KM2257 True RMS Digital Multimeter - 6000 Counts, VFD Mode, AutoV (LoZ), NCV Detection

The Kusam Meco KM2257 is a versatile True RMS digital multimeter, designed for precision measurements and user-friendly operation. With a high-resolution 6000 counts display, this multimeter is equipped with advanced features like AutoV (LoZ) for voltage measurement, VFD mode for accurate variable frequency drive measurements, and BeepJack™ input warnings for safe operation. The backlit LCD and non-contact voltage detection (NCV) enhance visibility and ease of use in low-light conditions. It is ideal for professionals in electrical diagnostics, HVAC, and industrial applications.

Key Features:

• True RMS Sensing: Accurate measurements for non-linear waveforms.
• AutoV (LoZ): Low impedance mode for precise voltage measurements.
• BeepJack™ Input Warnings: Alerts for incorrect terminal connections.
• Backlit LCD Display: Clear readings even in dim environments.
• MAX/MIN/AVG Recording Mode: Tracks measurement trends over time.
• Auto-Ranging with Relative Zero Mode: Automatically selects the best range and provides a reference point for relative measurements.
• EF-Detection (NCV): Allows detection of live wires without contact.
• VFD Mode: Optimized for accurate readings in variable frequency drive (VFD) systems.
