BEFORE TESTING
Checking the Display
Each time you turn on the OneTouch
®
Ultra
®
Meter either by inserting a test
strip or pressing the M button, all
segments of the display will appear
briefly. This tells you that the system is
performing several self-checks to confirm
that the meter is working properly. To
check that all display segments are
working, hold the C button down.
Coding the Meter
Code numbers are used to calibrate the
OneTouch
®
Ultra
®
Meter with OneTouch
®
Ultra
®
Test Strips for accurate results. You
must code the meter before using it for the
first time and then every time you change
to another vial of test strips. Each time you
test, check to be sure that the code
number on the meter display matches the
code number on the test strip vial.

CAUTION: Failure to code the meter correctly will cause
