Overview
The SZBJ BM820A is a versatile and robust digital clamp meter that combines the functions of a high-end multimeter with the convenience of a current clamp. Its standout feature is the ability to measure both AC and DC Current up to 600A using a non-invasive Hall Effect clamp. Equipped with True RMS for accurate readings on distorted waveforms and a high-resolution 5999-count display, this meter ensures that you capture even the smallest fluctuations in your system.
Key Features
High-Resolution 5999-Count LCD: Provides more precise readings compared to standard 4000-count meters.
Dual AC/DC Current Sensing: Measure up to 600A without cutting wires—essential for battery systems and solar inverters.
True RMS Technology: Ensures accurate measurement of non-sinusoidal signals (common in VFDs and computer power supplies).
Full Multimeter Functions: Measures AC/DC Voltage, Resistance, Capacitance, Frequency, and Temperature.
NCV & Continuity: Includes Non-Contact Voltage detection for safety and a fast-response continuity buzzer.
Data Hold & Backlight: Perfect for working in tight, dark spaces like electrical distribution boards.
