Troubleshooting BKT Error Codes: Your Definitive Guide
If you’re having trouble using your new BKT meter properly, don’t panic. Although receiving error codes can be frustrating, the good news is that most common errors are only a quick fix away. That’s why we’ve set up this definitive guide on BKT meter error codes and how to fix them.
What is an E-2 error code?
The E2 error code is one of the most common errors experienced with the BKT meter. It’s typically a result of your meter being set to the incorrect year, which can trick the device into believing that your test strips have expired. Thankfully, this error is easy to fix.
How to fix an E-2 error code
To fix an E-2 error code, all you have to do is press the S button (on the back of your device, next to the batteries) to switch your meter to “settings mode”. Once you’ve activated settings mode, use the M button (the big button on the front of the device) to toggle to the correct year and press S to confirm your choice. If you accidentally go past the current year, keep going until you hit 2050. The device will reset to 2005, giving you another chance to choose the current year.
Once you have the meter set to the correct year, continue the setup procedure until you’re finished with every option. To verify that your BKT meter is working properly, insert the keycard code that came with your test strips and wait for the meter to finish checking itself. When the meter displays the code, make sure that it matches the one on your ketone strips vial.
What is an E-U error code?
The E-U error code is caused by the meter believing a test strip has already been used. This is typically caused by accidentally getting blood on the test strip before inserting it into the device. Here are some tips to prevent receiving E-U codes in the future.
How to fix an E-U error code
To avoid getting blood on your test strips before inserting them, first make sure that your hands are freshly washed and thoroughly dried. In addition to preventing contamination, the warmth from washing your hands can make the blood flow easier.
With clean hands, insert a fresh strip into the meter and wait for it to finish checking the strip. Once it’s finished checking, the code matching the number on your vial of ketone strips will display on the screen, along with a flashing blood droplet icon. This signals that the meter is ready for a test.
Now, prick your finger with the lancet and wait 4 seconds before squeezing out a droplet of blood. Bring your finger to the test strip (still inserted in the meter) and allow the meter to collect your blood droplet. All you have to do now is wait for the meter to display your results!
What is an E-F error code?
When squeezing out blood for testing, it’s important to make sure that your blood droplet is big enough. Using a droplet that’s too small can result in an E-F (filling) error code, which can be often solved by collecting a bigger droplet for the test.
Sometimes, an E-F error can also be caused by pulling the strip away from your finger too soon or having an HCT result above 75%. Here’s a set of tips you can use to avoid getting E-F errors in the future.
How to fix an E-F error code
First and foremost, make sure your blood droplet is the adequate size -- around half the size of a matchstick head. Try adjusting the depth of your lancing device’s pierce to get a bigger drop of blood. Most lancing devices offer adjustible depths for different skin types, so experiment with the settings until you find the right one for you.
You can also try washing your hands in warm water or rubbing them together beforehand. This will increase blood flow in your fingertips, which can help you squeeze out an adequate drop of blood.
What is a PC Code?
Unlike other codes displayed by the BKT meter, a PC code isn’t actually an error code. This code is usually caused by a connection error of some sort, and there are two possible solutions for it.
How do I fix a PC Code?
If your BKT meter is having trouble syncing with your smart device via our app, try closing out the app and reopening it before attempting to sync again. This usually remedies the problem.
If you receive a PC code while a test strip is inserted into the meter, try removing the strip and putting it back in. Your meter may have been unable to properly connect with the test strip. Note that the meter cannot produce an accurate result while displaying a PC code, so be careful not to get any blood on the test strip until the issue is resolved.
Miscellaneous error codes and how to fix them
How to fix an E-b error code
An E-b error code signifies a low battery or a poor connection to the battery. This error code can usually be solved by swapping out or charging the meter’s batteries. If your batteries are new and you’re still experiencing this error code, make sure that the batteries are properly inserted into the meter or try using a different brand.
Having low batteries can create other error messages or cause your meter to produce inaccurate test results, so always make sure that your meter’s batteries are well-charged before testing.
How to fix an E-t error code
E-t errors, or temperature errors, are caused by being in an environment that’s too hot or too cold for the meter to function properly. The BKT meter is designed to operate in between temperatures of 50°F to 104°F (10°C to 40°C).
This error usually can be solved by moving to a warmer or cooler environment before testing again.
How to fix E-0, E-A, E-E or E-C error codes
These miscellaneous error codes can often be solved by turning your meter on and off again.
Try removing and re-inserting the batteries to restart the device, and follow the steps in our previous article for setting up the meter. Make sure the year is set correctly to avoid E-2 errors. Insert the code key that came with your test strips and wait for “CH” (this stands for checking) to appear on the screen.
After the meter is finished checking itself, your keycode should display on the screen. Verify that the code matches the one on your vial before inserting a test strip. After inserting a fresh test strip into your meter, wait for the device to display a code on the screen before testing.
