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.

AC/DC dual-useThe 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 switchingHigh 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. |
