Abstract
A magnetic field measuring apparatus including a magnetic sensor having an excitation winding and orthogonal first and second output windings for generating a first and a second output signal indicative of the orthogonal components of an external magnetic field, adjusting circuits for adjusting the amplitude and frequency of the sensor output signals, circuits responsive to common timing signals whereby the outputs of the adjusting circuit are subjected to sample-and-hold operation and A/D conversion and the resulting converted outputs are counted to generate count outputs, and a first and a second display unit for simultaneously displaying the count outputs.
