1. A method of acquiring calibrated electromagnetic field data using a probe and readout comprising the steps of:

  • a. acquiring electromagnetic field data using a multiple axis sensing probe;

    b. transmitting the field data in an uncalibrated form from the probe to a readout;

    c. calibrating the field data using a non-linear interpolation and linearization function by inserting predetermined values for coefficients into a curve-fitting equation previously used to calibrate a plurality of data points using a known field applied to the sensing probe; and

    d. presenting the calibrated field data to a user using the readout, wherein the field data is volts per meter (V/m) and the curve-fitting equation is of the form V/m=a+bxc where a, b, and c are the coefficients determined to linearize an uncalibrated data point “

    x”

    to provide calibrated volts per meter data.
