Core Functionality Evaluation
Triple-in-One Integrated Design
AC/DC Clamp Meter: Measures voltage (AC/DC), current (AC/DC), resistance, capacitance, and diode parameters. With True RMS (20,000 counts), it ensures precision in complex waveforms, ideal for industrial scenarios involving variable-frequency drives or harmonic-rich loads.
Oscilloscope Function: Simultaneously captures current and voltage waveforms. While bandwidth is unspecified, it suits general power system analysis, paired with a 2.8-inch IPS screen for dual visualization of waveforms and data.
Data Logger: Bluetooth connectivity to mobile apps (Android/iOS) enables remote control, data storage, and trend analysis, supporting long-term monitoring (e.g., energy consumption or fault tracing).
Smart Features & Safety
Threshold Alarm: Customizable upper/lower limits trigger alerts for overloads or automated quality checks.
Hardware Design: Full-button operation and a slim jaw design enhance accessibility in tight spaces (e.g., dense wiring in cabinets) and compatibility with large cables.
