Current measurement from isolated probing of conductor Dynamic range of 10mA to 20A peak to peak Wide bandwidth of DC to 5MHz Low noise equivalent to <6mA rms Safety rated to 300V Cat II Suitable for connection to any oscilloscope High accuracy general purpose H-field probe Convertible into 'closed magnetic circuit' current probe No requirement to break or surround the conductor Observe and measure currents in PCB tracks directly Minimal disturbance to circuit conditions through very low insertion impedance and stray capacitance Useable in confined and difficult to access spaces Measures current into surface mount components, IC legs and short component leads Can observe currents flowing within ground planes Useable on high voltage conductors and in high temperature areas
The Aim-TTi I-prober 520 is a unique current measurement device. Measurement of current normally requires it to be passed through a closed magnetic loop, typically using a split clamp device. Whereas this is suitable for individual wires, it is of no use for measuring current in PCB tracks. The I-prober 520 uses positional H-field measurement. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured. The I-prober 520 is supplied with a clip-on toroid assembly which converts it into a closed magnetic circuit probe for measuring current within a wire.
