7. Measurement
7-1 Measurement condition
The reference temperature shall be 25°C ± 2°C. The measurement shall be
performed in the temperature range of 5°C to 35°C unless result is doubtful.
7-2 Measurement circuit and equipment
7-2-1 Oscillation frequency shall be measured by the standard test circuit as
shown below.
7-2-2 Resonant impedance and anti-resonant impedance shall be measured by the
impedance meter (HP-4194A).
7-2-3 Capacitance shall be measured by the Universal Bridge (CCJ-1C).
