Abstract

PURPOSE:To automatically determine the number of addition times in order to obtain prescribed SN by providing a means for measuring the Q value of a high-frequency coil at the time of no load and at the time of installation of an object to be inspected, means for calculating the SN of a reception signal and means for determining the number of addition times of the reception signal. CONSTITUTION:The high-frequency coil 4 is subjected to frequency sweeping at the time of no load and the generated magnetic field intensity is detected by a small-sized coil 13. The output voltage of said coil is inputted via an amplifier 14 to a calculator 11. The calculator 11 measures the Q value and sensitivity index of the coil 4 at the time of no load from said voltage. The Q value of the coil 4 at the time of installation of the object to be inspected is then measured and the SN of the reception signal obtd. from the coil 4 is calculated by using the prescribed equation. The required and sufficient number of addition times of the reception signal is further calculated from the SN in order to obtain the satisfactory SN of the signal. The number of addition times determined in such a manner is automatically transferred to a sequence control circuit. The number of addition times is thereby automatically and efficiently determined.
