Accu-Chek Active Code 333 & Black Activation Chip Guide

Accu-Chek Active code 333 black activation chip and no-coding meter guide

If you use an older Accu-Chek Active glucometer, you may have encountered terms such as code 333, black activation chip, green code chip or no coding.

These terms relate mainly to different generations of the Accu-Chek Active blood glucose monitoring system and the transition from older coded meters to the newer no-coding system.

Quick answer: Current Accu-Chek Active systems do not require manual coding. Some previous-generation Active meters use a permanent black activation chip. On those older meters, code 333 may still appear because it is programmed into the meter software and does not mean that the user needs to enter or change code 333 manually.

What Does “Coding” Mean on a Glucometer?

Some older blood glucose monitoring systems used a code chip or coding process so that the meter and the batch of test strips could work together correctly.

With those older systems, customers might have seen a removable chip supplied with the test-strip packaging.

Modern Accu-Chek Active systems use a no-coding approach, making the testing process simpler for the user.

Does the Current Accu-Chek Active Meter Require Coding?

No. Current Accu-Chek Active meters do not require users to manually enter a test-strip code during routine blood glucose testing.

This is why customers purchasing a current Accu-Chek Active meter may not find the same code-chip arrangement described in older online instructions or older videos.

When using a current meter, follow the user manual supplied with that exact meter rather than assuming instructions for a previous generation still apply.

Why Do Older Accu-Chek Active Meters Have a Code Chip?

Previous generations of the Accu-Chek Active system used a green code chip supplied with test strips.

As the Active system transitioned toward no-coding operation, Accu-Chek introduced a black activation chip for compatible previous-generation meters.

The black activation chip replaced the older green coding arrangement for those meters.

What Is the Accu-Chek Active Black Activation Chip?

The black activation chip is used with certain previous-generation Accu-Chek Active meters.

Its purpose is to permanently configure the older meter so that it can work as a no-coding meter with the applicable newer Accu-Chek Active test strips.

After the correct black activation chip is inserted into the older meter, it normally remains in the meter.

It is not intended to be replaced every time a new vial of current Active strips is opened.

Black Activation Chip vs Green Code Chip

Chip	Purpose	What the User Does
Older Green Code Chip	Part of the older test-strip coding system	Used according to instructions for the older strip batch/system
Black Activation Chip	Upgrades applicable older Active meters for no-coding operation	Insert and leave it in the older meter
Current No-Coding Meter	Designed without routine strip coding	No manual strip-code entry required

Does the Black Activation Chip Need to Be Changed?

For an applicable previous-generation Accu-Chek Active meter, the black activation chip is intended to remain installed.

It does not normally need to be changed when opening another vial of current compatible Accu-Chek Active strips.

If another chip is found in a later vial, users of the correctly upgraded older meter should follow the current Accu-Chek instructions for that system rather than repeatedly changing the permanent activation chip.

What Does Code 333 Mean on Accu-Chek Active?

Some previous-generation Accu-Chek Active meters may display code 333 when they are switched on.

According to Accu-Chek, this is a programmed software function of the older meter.

It does not mean that you need to:

enter 333 manually before every test,
find test strips with 333 printed on them,
match every new strip vial to code 333, or
change the black activation chip every time you buy strips.

If the appropriate older Active meter has been set up with its black activation chip, code 333 may simply remain visible as part of the programmed meter behaviour.

Is Code 333 a Test Strip Compatibility Code?

No. Customers should not treat 333 as a universal compatibility number for choosing Accu-Chek Active test strips.

The important compatibility rule is:

Accu-Chek Active Meter → Accu-Chek Active Test Strips

Do not choose test strips merely because an online listing, photograph or old meter screen mentions a particular number.

Do New Accu-Chek Active Meters Show Code 333?

The code-333 discussion mainly relates to previous-generation Accu-Chek Active meters.

Current no-coding Active meters use the newer system and do not require the older removable code-chip process for routine testing.

Can Newer Active Strips Work with an Older Accu-Chek Active Meter?

Accu-Chek states that applicable previous-generation Active meters can be upgraded to no-coding operation through the black activation chip.

Once the correct black activation chip is installed and retained in the older meter, the system is designed for use with the applicable newer Accu-Chek Active test strips.

Because several Active generations have existed, anyone using a very old meter should check the exact model and manufacturer instructions before relying on general online advice.

Does the Black Activation Chip Affect Glucose Accuracy?

Accu-Chek states that use of the black activation chip does not change the accuracy of the blood glucose measurement.

Its purpose is related to upgrading the coding arrangement of compatible older meters, not changing the intended measurement performance of the system.

What Changed After Installing the Black Activation Chip?

One important change concerns the old automatic test-strip expiry warning.

Older coding arrangements could transmit expiry information through the code-chip system. After an older meter is converted using the black activation chip, that automatic expiry warning is no longer available.

Users therefore need to check the expiry date printed directly on the Accu-Chek Active strip vial.

Does the Current No-Coding Accu-Chek Active Meter Warn About Expired Strips?

No. The current no-coding system does not rely on the old code chip to provide an automatic strip-expiry warning.

Check the printed expiry or use-by date on the physical strip vial before testing.

Can Old Orange Accu-Chek Active Strips Be Used with the No-Coding Meter?

No. Accu-Chek advises customers not to use the older orange Accu-Chek Active test strips with the no-coding Active meter.

This is particularly important for customers who have retained very old test-strip stock or an older generation of the Active system.

Do not assume that every historical product carrying the words “Accu-Chek Active” is automatically suitable for every later-generation Active meter.

How Do I Know Which Accu-Chek Active Strips to Buy?

For customers using the current Accu-Chek Active system, the simplest rule is:

Choose current Accu-Chek Active Test Strips intended for the Accu-Chek Active meter.

Microsidd currently maintains dedicated listings for several Active strip quantities.

Should I Remove the Black Activation Chip from an Older Meter?

If you have an applicable previous-generation Active meter that uses the black activation chip, Accu-Chek advises that the chip should remain in the meter.

Do not repeatedly remove and replace it merely because a new vial of test strips has been opened.

What If I Lose the Black Activation Chip?

If an older meter generation requires the black activation chip and the chip has been lost, do not guess which chip or code should replace it.

Check the exact meter generation and contact Accu-Chek support or follow the manufacturer instructions applicable to that meter.

Because current meters use a different no-coding design, advice for a new meter should not automatically be applied to an older meter that originally used an activation chip.

How Can I Tell Whether My Accu-Chek Active Meter Is an Older Generation?

Older Active systems may have a physical code-chip slot or may already contain a black activation chip.

Current no-coding meter versions do not use the same removable code-chip arrangement.

If you are uncertain, check:

the exact meter model,
the user manual supplied with the meter,
the physical code-chip area of the device, and
current Accu-Chek support information for that generation.
