The Accu-Chek Compact Plus blood glucose meter checks each test strip for quality before a test. Because of this check, the meter’s test strip advancing mechanism needs to pause briefly before ejecting the test strip completely. If the test strip is ruined, an error message appears.

Warning: The test strip quality check can only check the test strip, not the whole system. (When the meter boots, the electronics and battery will be checked). For this reason it is not possible to completely eliminate performance checks in addition to the inbuilt test strip quality check. Checks are made to ensure that the test area changes color in a particular way, e.g., when moistened.
