SZBJ BM803A+ Digital Clamp Meter – High Precision AC/DC Current & Voltage Multimeter with NCV

Overview

The SZBJ BM803A+ is more than just a basic clamp meter; it is a high-precision diagnostic tool designed for complex electrical systems. Unlike cheaper models that only measure AC current, the BM803A+ features a Hall Effect sensor, allowing it to measure DC Current as well. True RMS technology, it provides accurate readings even on “noisy” non-sinusoidal waveforms found in modern variable frequency drives (VFDs) and switching power supplies.

Key Features 

• AC/DC Current Measurement: Large 30mm jaw opening allows you to measure current in thick cables without physical contact.

• True RMS Accuracy: Provides precise measurements regardless of waveform distortion.

• NCV (Non-Contact Voltage) Detection: Built-in sensor lets you detect live wires behind walls or in panels without touching them.

• Large Backlit Display: 3999 count LCD with a clear backlight for working in dark electrical cabinets.

• Temperature & Frequency: Includes a K-type thermocouple for temperature testing and frequency measurement for motor diagnostics.

Technical Specifications

Why “A+” vs. Standard Models?

• Hall Effect Sensor: This allows for the DC Current function, which is essential for solar panel (PV) installations and automotive troubleshooting.

• Auto-Ranging: The meter automatically selects the best range for your measurement, preventing “blown fuses” or incorrect readings.

• Capacitance Testing: Ideal for HVAC technicians checking motor start capacitors.
