Fix the capacitor to the supporting jig in the same
manner and under the same conditions as (10).
Perform the five cycles according to the four heat treatments
shown in the following table.
Set for 24T2 hours (temperature compensating type) or 48T4
hours (high dielectric constant type) at room temperature, then
measure.
