If a used test strip drum is inserted the code on the test strip drum is first read automatically. The Accu‑Chek Compact Plus blood glucose meter then searches for the next chamber containing a test strip, always starting with the first one. For example, if just 1 test strip is left in the test strip drum, the meter checks 16 chambers before it finds the last test strip.

Warning: The 90-day period quoted for using up the test strip drum is no longer valid because the test strip drum compartment was opened, and the meter can no longer recognize how long the test strip drum was used (see “Error messages” in the User’s Manual)
