Test or Inspection Method
Temperatures Coefficient
The temperature coefficient is determined using the
capacitance measured in step 3 as a reference. Test the
specimen from step 1through step 5, the capacitance shall
be within the specified tolerance for the capacitance
coefficient and capacitance change as left table.
