TRONOVO TR3031M 100A 500kHz Split-Type AC/DC Current Probe

The TRONOVO TR3031M is a split-type AC/DC current probe for measuring current waveforms with an oscilloscope. It provides DC to 500kHz bandwidth, selectable 100mV/A and 10mV/A sensitivity, and peak-current coverage from 50mA to 100A across its two ranges.

The separate clamp head is designed to reach conductors in confined or densely wired areas, while the external control module keeps range selection and zero adjustment accessible. A standard BNC output connects directly to compatible oscilloscopes.

Key Features

• DC–500kHz bandwidth: Measures both steady DC current and changing AC current waveforms.
• Up to 100A peak: The 10mV/A range covers 1A to 100A peak current.
• Dual sensitivity: Select 100mV/A for 50mA to 10A peak measurements or 10mV/A for 1A to 100A peak measurements.
• Split-type design: A compact remote clamp head supports access in crowded test setups.
• Automatic and manual zeroing: Supports fast setup and fine baseline adjustment.
• Overload indication: An audible alarm indicates when the measured current exceeds the selected range.
• 13mm jaw opening: Clamps around conductors up to 13mm in diameter without breaking the circuit.
• Standard BNC output: Connects to oscilloscopes without a proprietary signal adapter.
• USB Type-C power: Operates from a DC 5V/2A Type-C supply.
• Safety ratings: Rated for 600V CAT II and 300V CAT III measurement environments.

Typical Applications

• Switch-mode power supply waveform analysis
• Motor-control and drive-current measurements
• Inrush and startup current testing
• Power-electronics development and troubleshooting
• Automotive-electronics current measurements
• Laboratory instruction and circuit analysis

Range Selection

Use the 100mV/A setting for smaller signals from 50mA to 10A peak. Select 10mV/A for higher-current measurements from 1A to 100A peak. Confirm the selected range, zero the probe, and observe the published voltage and current limits before measurement.

Safety Note

Operate the probe only within its specified current, voltage and measurement-category limits. Follow the current TRONOVO manual and applicable electrical-safety procedures when working on energized circuits.
