The DT-9382 and DT-9382B represent the premium tier of clamp meters, combining top-tier measurement capabilities with advanced visualization and connectivity features. Both models feature a vibrant 1.8" TFT color LCD display, True RMS measurement, and support for an optional flexible 3000A current clamp. The key distinction is the Bluetooth data connectivity present in the DT-9382, which is absent in the DT-9382B.
Key Features Common to Both Models (DT-9382 & DT-9382B):
Premium Color Display: Large 1.8-inch TFT color LCD with 6000-count resolution provides exceptional clarity for numeric readings, trend graphs, and menu navigation.
AC/DC Clamp & True RMS: Measures both AC and DC current up to 1000A via the rigid jaw, with True RMS accuracy for correct readings on distorted waveforms.
Extended Current Range (Optional): Supports an optional flexible current probe (AC only) that extends the measurement range up to 3000A, ideal for large conductors and busbars.
Advanced Data Visualization & Logging:
Trend Capture Function: Graphically plots measurements (e.g., current, voltage) over time directly on the color screen to identify fluctuations and patterns.
Data Review: Stores and allows review of the last 100 graph screenshots for post-analysis.
Full-Featured Multimeter: Measures AC/DC Voltage (1000V), Resistance (60MΩ), Capacitance (100mF), Frequency (10kHz), and Temperature.
Comprehensive Diagnostic Suite: Includes Inrush Current, Low Impedance (LoZ) Mode, Low Pass Filter (LPF), Non-Contact Voltage (NCV), flashlight, data hold, and relative function.
Rugged Design: Double-molded housing with a standard 35mm jaw.
