TR3031C

100A/1.5MHz AC/DC current probe

TR3031X series is the 1 universal oscilloscope current probe, compatible with more than 95% of oscilloscopes on the market, with a frequency response measurement range of 50mA to 100A (peak value) up to 5MHZ, and BNC output terminals. Connect an oscilloscope to accurately measure AC or DC current waveforms, with a selectable range on the handle panel; the current probe detects the current flowing through the conductor and converts it into a voltage that can be seen and measured on the oscilloscope. The current probe uses a hybrid technology including a Hall effect sensor (sensing DC current) and a current transformer (sensing AC current). The open design current probe is easy to connect and disconnect from the conductor, providing a DC to 5.5MHz measurement bandwidth.

Product Features
• Intermediate frequency upgrade performance: 1.5MHz bandwidth breakthrough upgrade, 230ns rise time to capture relay switching transients
• Long-term battery power supply: 9V battery 13 hours of life (low red light warning), mobile detection without external power supply
• Precise phase control: DC ~ 65Hz phase shift <1.5 ° to ensure distortion-free acquisition of photovoltaic inverter waveforms
• Compact field adaptation: 230mm ultra-short clamp body, flexible deployment in narrow space of cabinet

AC/DC dual-use

The TR3031C adopts industry standard BNC interface design, perfectly adapts to brand oscilloscopes such as Keysight (is Germany Technology), Tektronix (Tektronix), Rohde & Schwarz (Rohde and Schwarz), saves complicated adapters, starts up and measures, multiplies efficiency, and covers DC-low frequency AC completely. Based on Hall effect principle, the TR3031C can simultaneously measure direct current (DC) and alternating current (AC)1.5MHz current signals, accurately present the complete current trace from static operating point to dynamic change.

Double gear wide free switching

High sensitivity gear (100mV/A): focus on small current (7A RMS/10A peak value), resolution up to milliampere level, accurate analysis of standby power consumption and micro current ripple; High load gear (10mV/A): cope with large current (70A RMS/100A peak value), strong anti-interference, stable measurement of motor drive and inverter peak current.

Humanized operation design

One-key automatic zero adjustment (AUTO ZERO), elimination of DC drift in seconds, automatic elimination of temperature drift and remanence interference within 3 seconds after pressing the button, ensuring "starting from zero" for each measurement, dual indicator light system, real-time visual of power supply/overload status, jaw opening and closing diameter of 11.8mm, clamping of thick wires such as motor cables and power bus bars without disassembly.

Dual mode power supply

Support USB adapter (5V/2A), mobile power supply or 9V dry battery power supply, suitable for laboratory, field, high-altitude operations and other all scenes, field without socket can continue to work.

Transient test

When the motor is turned on, the starting current soars to several times the rated value, with the peak value lasting only 20-100ms, even us level, accurately capturing the current spike ≤ 230ns.
