PROBLEM TO BE SOLVED: To transmit the output from a current probe to a receiver without wires for measuring. SOLUTION: A battery 105 supplies power to each block through voltage regulators 110, 115, and 120. A hall effect sensor 125 generates a signal representing the current to be transmitted to a tested conductor while a signal conditional circuit 130 offsetting and scaling the current signal to generate a conditional signal. An ADC 135 samples the conditional signal, generates digital signal sample, and processes the digital signal sample with a microcontroller 140. An RF datalink 145 performs communication between the microcontroller and a receiving unit. COPYRIGHT: (C)2011,JPO&INPIT
