During each measurement the coded meter performs the
essential checks automatically. Since each code strip and test
strip is characterized by a bar code on the back, the meter
recognizes whether a blood glucose (GLUC) or cholesterol
(CHOL) strip is being used. It then checks automatically
whether the code number on the inserted test strip is the same
as the code number it has stored. If the wrong test strip is
inadvertently used, the error message
e-1
appears.
