The temperature coefficient is determined using the
capacitance measured in step 3 as a reference.
When cycling the temperature sequentially from
step 1 through 5 the capacitance should be within
the specified tolerance for the temperature coefficient
and capacitance change as in Table A-1. The
capacitance drift is calculated by dividing the
differences between the maximum and minimum
measured values in steps 1, 3 and 5 by the cap.
