"yes", a log is printed out at the same time.
NOTE
The intensity of the color change of the treatment indicator tape often varies between batches due
to different storage periods or other influences. What is critical when assessing the Bowie & Dick
test is not the intensity of the color change but instead the uniformity of the color change on the
test strip.
If the treatment strips or treatment indicator tape has changed color evenly, the ventilation of the
sterilization chamber is functioning correctly.
If the center of the star on the treatment indicator strips or treatment indicator tape has not
changed color or the color change is less than on the ends, the ventilation was inadequate. In this
case, contact your supplier's customer service.
