Before Testing

Checking the Meter Display

Each time you turn on the OneTouch® Ultra® Meter either by inserting a test strip or

pressing the 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, with the meter off, press the

button and immediately hold the 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: Matching the code on the meter and the code on the test strip vial is essential to obtain accurate results. Each time you test, check to make sure the code numbers match.
