The CoaguChek XS Error 3 is a general error code that can be caused by a number of different factors. Some of the most common reasons for this error code include:

-The test strip being inserted into the meter incorrectly

-The test strip being damaged or expired

-The meter not being calibrated properly

-The meter being used in an environment that is too hot or too cold

-The meter being used with expired or damaged batteries

If you are getting this error code, it is important to first check to see if the test strip is inserted correctly. If it is, then you will need to check the expiration date on the strip and make sure that it is still valid. If the strip is expired, then you will need to get a new one.

If the test strip is not the issue, then you will need to check the calibration of the meter. If the meter is not calibrated properly, then it will not give you accurate results. Make sure to follow the instructions in the manual on how to properly calibrate the meter.

If the meter is still not working after these steps, then it is likely that the environment that you are using it in is too extreme. Make sure that the meter is not being used in an area that is too hot or too cold. If the meter is still not working, then you may need to replace the batteries.
