Introduction
The ACCU-CHEK
®
Go blood glucose system is a state-of-the art precision instrument that will
enable you to test blood glucose simply and with confidence. The blood glucose meter is designed
and approved to quantitatively measure the concentration of glucose in capillary whole blood
samples outside the body (
in vitro diagnostics use) by healthcare professionals, or persons with
diabetes, for monitoring glucose in healthcare facilities, or in the home. It should not be used to
diagnose diabetes. This user’s manual contains the complete instructions for using the system.
No matter whether this is your first time using a blood glucose meter or whether you have used
others in the past, please take time to read this manual carefully and completely before
performing the first blood glucose measurement. The manual may tell you a lot of what you
know already, but it will also introduce many features that may be new to you. To use the meter
correctly and dependably, you need to have a thorough understanding of the way it operates,
what the screen displays mean, and the individual functions.
Should you have any questions, the ACCU-CHEK Customer Care service center is available 24
hours a day. Call 1-800-440-3638.
To start testing quickly, you can also refer to the ACCU-CHEK Go Quick Reference Guide.

Connecting (or Changing) the Battery
The ACCU-CHEK Go meter is sold complete with one lithium battery (type CR2430 or DL2430) already inserted.
A plastic film protects the battery against becoming drained prematurely. Before using the meter, remove the
film covering the battery as follows:
1. Use your thumb to slide the battery tray up and out of the meter.
2. Remove the plastic film and throw it away.
3. Slide the battery tray back into the meter until it locks in place.
A new battery provides enough power for about 1,000 tests
in a year.
To change the battery, remove the old battery and place the new one in the tray with
the + side facing down.
• The battery symbol on the screen means the battery is low and should be changed
soon.
• When the battery symbol appears for the first time, it indicates that the battery is wearing
down. You can perform approximately 50 additional tests, however, we recommend that
you replace the battery as soon as possible.

NOTE: If you do not set the date and time, a series of zeros will be displayed when you take a reading.

only use data stored together with the date and time. To distinguish readings in the memory, they are numbered
consecutively.
