By a large number of experiments when the L1 coil excitation frequency around 14 kHz, the maximum sensor resolution

Through extensive experiment when the L1 frequency coil excitation at 14 kHz or so time, sensor resolution maximum

Through the massive experiments obtains when L1 coil excitation frequency when 14 kHz, the sensor resolution is biggest

Through much experimentation with L 1coil inspired kHz frequencies in 14, when resolution of sensor around the largest

Through extensive experiment when the L1 frequency coil excitation at 14 kHz or so time, sensor resolution maximum
