Initial steps before testing2
Validity of the test cassette
When a test cassette is in the meter, the meter checks
regularly when the cassette was inserted and calcu-
lates the use-by period from this. Each test cassette
must be used up within 3 months (use-by period). If
you insert a partly used test cassette into the meter,
the use-by period is calculated from the date when the
cassette was placed in the meter for the rst time. This
date is stored in the cassette.
The meter also checks whether the expiry date of the
cassette has been reached. The expiry date is shown
on the box of the test cassette and on the lid lm of the
foil-sealed packaging next to the symbol
.
If either of the two dates – use-by period or expiry date
– is exceeded, the validity of the cassette has expired.
You cannot perform any more tests with this test cas-
sette.
