PI CIRCUIT FIXTURE FOR MEASURING VIBRATOR

PROBLEM TO BE SOLVED: To realize a π circuit fixture for measuring vibrators which is capable of measuring a vibrator requiring a load capacity easily and quickly. SOLUTION: This π circuit fixture 100 for measuring vibrators is provided with 1,101st and 2102nd π circuits connected to both ends of a vibrator 104 as object to be measured. A variable capacitance element D1 is provided between a connection terminal to which the vibrator is connected and either a first or second circuit, a capacitance decision means 103 to determine the capacitance of the variable capacitance element D1 and an insulating means between the variable capacitance means and the capacitance decision means to insulate the means on an AC basis or electrically.
