How to use the Accu-Chek Compact Plus blood glucose meter

The Accu-Chek Compact Plus meter is easy to operate. Its integrated Accu-Chek SoftClix Plus finger pricker enables the user to test anywhere.

Testing blood glucose

  • Pull down the central test button to release a test strip. The meter will turn on automatically. 
  • Hold the meter so the test strip is pointing downwards. Touch the drop of blood against the front edge of the test strip where the black notch is located. The strip draws the blood. The display should flash an image of a test strip and blood drop. 
  • See display for meter reading. 
  • Pull down the central test button to eject the used test strip.

How to insert or replace a test-strip drum

  • Open drum compartment cover. 
  • Press the red drum release button. 
  • Tip the meter forwards, the test-strip drum drops out. 
  • Insert new test-strip drum.

Accu-Chek Compact Plus frequently asked questions

Can rechargeable batteries be used?

Yes. Since rechargeable batteries normally have a voltage of 1.3 V instead of 1.5 V, the measurement cycles will be reduced. Additionally, the discharging characteristics are completely different, therefore it must also be remembered that when the battery icon appears the minimum safety buffer of 50 measurements can no longer be guaranteed.

Can the Accu-Chek Compact Plus system be used in the professional sector (hospital)?

No it cannot because if the meter is held upwards instead of downwards when drawing up blood, there is a risk of blood running into the casing. When the next strip is ejected, it may be contaminated by the blood that entered earlier. Then there is a risk of cross contamination.

Can the brightness of the new OLED display be adjusted?

Yes, by pressing the “S”-button, the second step within the setup mode is the adjustment of brightness. Three levels are selectable with “M”-button.

Can the strip also be removed manually?

The ejected strip can be removed manually without damaging Accu-Chek Compact Plus. However, by removing a used strip manually there is a risk of contamination, so this should be done only in exceptional circumstances.

Can the system be used for neonates?

The system cannot be used for neonates.

Can Compact Plus Test Strips be purchased?

Compact Plus Test Strips are available on prescription.

Does the Accu-Chek Compact Plus meter need to be cleaned?

The Accu-Chek Compact Plus Meter does not require cleaning if it is handled as instructed. However, if it is misused (e.g. the ejected strip is not held slanting downwards when drawing up blood or control solution) the optics part can become dirty.

Does the Accu-Chek Compact Plus system offer the opportunity to re-dose after blood has been applied?

Yes, the Accu-Chek Compact Plus system has a re-dosing option within 25 seconds.

How long do the batteries last?

High energy batteries last approximately 1,000 measurements or one year. The internal clock uses power irrespective of the number of measurements, even when the Accu-Chek Compact Plus meter is switched off. The number of measurements may be reduced when the measurement frequency is extremely low (1 measurement per week) and the meter is left unused. The number of measurements may be improved where the measurement frequency is high.

How reliable is the barcode reader?

The bar-code reader has an automatic error detection which meets the highest reliability standards. 

If an error is detected, an error message appears. The customer should then proceed as described in the instructions and take another drum from the same package to continue with his / her measurement (see the section on error messages in the instructions for use). 

All drums produced by Roche have been tested and passed 100% by video control.

Is it possible to insert the drum incorrectly?

No, it is not possible to insert the drum the wrong way. The Accu-Chek Compact Plus meter has been designed to enhance safety.

Is the measurement result affected by altitude?

The Gluc-Dor enzyme used has a negligible dependence on the atmospheric oxygen level. For this reason its altitude dependence is also extremely small. We guarantee full functionality for up to 4000 m.

Is the OLED display readable in bright sunlight?

No. The readability in bright sunlight is a disadvantage of the OLED. By shading the display it is readable again.

Is underdosing possible and how reliable is the control mechanism?

The strip has a capillary design so that measurement does not start until there is sufficient blood in the capillary. A symbol has also been incorporated to show when measurement starts. In the event of underdosing, measurement does not start or the error message appears when the test strip is not redosed within 25 seconds.

What happens if a used drum is inserted?

If a used drum is inserted the code on the drum is first read automatically. The Accu-Chek Compact Plus meter then searches for the next chamber containing a strip, always starting with the first one. For example, if just 1 strip is left in the drum, the meter checks 16 chambers before it finds the last strip. 

 Warning: The period quoted for using up the Accu-Chek Compact drum is no longer valid because the drum compartment was opened (see "Error messages" in the Reference Manual).

What is the strip quality check? How does it work?

The Accu-Chek Compact Plus system checks each strip for quality before measurement. Because of this check, the meter’s strip advancing mechanism needs to pause briefly before ejecting the strip completely. If the strip is spoilt, an error message appears. 

Warning: The strip quality check can only check the strip, not the whole system (meter, meter optics). For this reason it is not possible to completely eliminate performance checks in addition to the inbuilt strip quality check. Checks are made to ensure that the test area changes colour in a particular way, e.g., when moistened.

Why does the user have to wait until the strip and drop icon appears in the display before testing?

The meter is performing the strip quality check. Strip position and other details are tested before the strip is advanced. The total time required is about 1.5 seconds.

Why does the Accu-Chek Compact Plus strip advancing mechanism stop briefly before the strip reaches the measuring position?

The meter is performing the strip quality check. The total time required is about 1.5 seconds.

Why must the drum be left in the Accu-Chek Compact Plus Meter for no more than 90 days?

All test strips are moisture-sensitive. The drum contains a desiccant which protects the strips from moisture for 90 days (in all climatic zones). After that time the desiccant is used up and the strips are exposed to moisture. They become unusable after just a few days. An additional desiccant protects the strips in the unopened tube until the printed expiry date. 

When a drum is placed in the Accu-Chek Compact Plus Meter, the display shows the drum icon and "control bottle" after 90 days. This means that the drum can no longer be used. If the drum continues to be used, the Accu-Chek Compact Plus prompts the user to perform a control check. Medically, the strips should not be used. If they are, the readings obtained must be used for guidance only. The meter registers every opening of the cover and sets its internal timer to 0, i.e. the message "Drum-Icon + Control-Bottle-Icon" appears. To prevent incorrect results, the quality of each strip is also checked again before it is used (see "strip quality check").

Why should the batteries be changed only when the drum is also changed?

Each battery change is a break in the power supply. This means that Accu-Chek Compact Plus meter does not know whether or not the cover was opened and the drum was changed. In this case the meter assumes, for safety reasons, that the cover was open and reads the code again. Accu-Chek Compact Plus accesses the first chamber and if this is empty the meter identifies the drum as having been used. 

Another old, used drum could have been inserted during the battery change. That is why, for safety reasons, the Accu-Chek Compact Plus meter now prompts the user to carry out a performance check.
