The meter cannot calculate the
use-by period for this test drum.
• A partly used test drum was
inserted,
• The drum compart ment cover
was opened and closed with a
partly used test drum inside,
• The time and date settings
were lost when the batteries
were changed with a partly
used drum inside and
changing the batteries took
longer than 2 minutes.
See Chapter 1, "Installing the
Test Drum."
The meter is ready to transfer
results to a computer. See
Chapter 4, "Meter Memory and
Transferring Results."
No result is stored in the
memory.
Averaging is not possible
because
• time and date are not set,
• memory only contains results
without a time and date,
• memory only contains results
that are not included in the
calculation, e.g. control results,
• no results were saved in the
period in question.
Battery power is low. The first
time the message appears, about
50 tests can still be performed. –
Change the batteries soon. See
Chapter 6, "Changing the
Batteries."
If the battery symbol appears
briefly and the display goes
blank, the batteries are too low
to perform any more tests. –
Insert new batteries.
