Understanding i-Sens CareSens N Meter Error Codes

CareSens N Meter Error Codes - System Errors: Er1 - Er6:

Unlike meters such as the Ascensia Contour Next One, CareSens N Meter error codes are relatively limited in number making it simple to diagnose problems. There are only 6 error codes which start with "Er" and end in a number.

Error Code 1 (Er1) - Used Test Strip

Er1 will be displayed if the meter detects a used test strip.

Solution: Remove the used strip and replace it with a new one. Make sure to use a fresh test strip for an accurate reading.

Error Code 2 (Er2) - Strip Inserted Too Early

Er2 means the blood or control solution sample was applied before the insert symbol appeared. 

Solution: Remove the used strip and repeat the test with a new test strip and wait until the symbol appears before applying the blood or control solution sample. Make sure to use a fresh test strip for an accurate reading.

Error Code 3 (Er3) - Temperature Out of Range 

Er3 indicates the temperature during the test was above or below the operating range.

Solution: Move to an area where the temperature is within the operating range (50 - 104˚F) and repeat the test after the meter and test strips have reached a temperature within the operating range.

Error Code 4 (Er4) - Blood Sample Issue

Er4 signifies the blood sample has abnormally high viscosity or insufficient volume. 

Solution: Repeat the test using a new test strip.

Error Code 5 (Er5) - Wrong Test Strip

Er5 means the wrong blood glucose test strip is used. 

Solution: Repeat the test with a CareSens N Test Strip. Insert the strip with the contact bars facing up, and push in gently until the meter turns on.

Error Code 6 (Er6) - Hardware Problem

Er6 means there is a problem with the meter.

Solution: Do not use the meter. Contact Customer Service: 1-800-429 5001.

CareSens N Meter Error Codes: How to Avoid Them

Now that you know what the error codes mean, here's how you can avoid common errors with your CareSens N meter and test strips.

• Make sure you are using the correct test strips. The CareSens N Blood Glucose Monitoring System only works with CareSens N Test Strips. Using the wrong test strips can result in inaccurate results.
• Store your test strips properly. Test strips should be stored in a cool, dry place. Avoid exposing them to direct sunlight or extreme temperatures.
• Use a fresh test strip for each test. Do not reuse test strips.
• Apply enough blood to the test strip. If you do not apply enough blood, the meter will display an error code.
• Insert the test strip correctly. The test strip should be inserted into the meter with the contact side facing up.
• Wait for the meter notification before removing the test strip. Do not remove the test strip too early, as this can result in inaccurate results.
• Clean the meter regularly. Wipe the meter with a damp cloth after each use.

CareSens N Meter Error Codes: Additional Tips

• Wash your hands before testing. This will help to prevent dirt and bacteria from contaminating your blood sample.
• Choose a finger that is clean and dry. Avoid testing on fingers that are swollen or have wounds.
• Prick your finger on the side. This is the least painful area to prick your finger.
• Massage your finger gently. This will help encourage blood flow.
• Apply the blood to the test strip immediately. Do not let the blood dry before applying it to the test strip.

By following these tips, you can help to avoid common errors and ensure accurate results with your CareSens Meter.
