Averaging results
STIPA measurements require averaging of STI/CIS indexes. This averaging concerns two aspects:
1) averaging of results for a measurement
point.
Averaged STI / CIS for the measurement point
is displayed in the left upper corner of the
Point view and in the measurement points list
of the Area view.

2) averaging of results for a tested area.
Averaged STI / CIS for the tested area is
displayed in the left upper corner of the Area
view and in the second line of the Area
summary view.

According to most standards, it is good practice to average the results for measurement points for two or three
measurements. In case of noise fluctuations during measurements, it is recommended to make not less than
three measurements and check whether the spread of the STI index does not exceed 0.03.
