Frequently Asked Questions

General questions

Yes. Since rechargeable batteries normally have a voltage of just 1.3 V instead of the AAA batteries’ 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. In addition, we do not have any control over the quality of the rechargeable batteries nor the recharger.

The test strip has a capillary designed so that the test does not start until there is sufficient blood in the capillary. A symbol has also been incorporated to show when the test starts. In the event of under-dosing, the test does not start or the error message appears when the test strip is not re-dosed within 25 seconds.

Yes, but you need to manually flag the control measurement.

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

Warning: The 90-day period quoted for using up the test strip drum is no longer valid because the test strip drum compartment was opened, and the meter can no longer recognize how long the test strip drum was used (see “Error messages” in the User’s Manual)

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

Since the batteries do not complete the circuit and the meter is not turned on, nothing can be damaged.

No. The meter cannot be used for neonates.

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

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

Since the 17-test-strip-drum determines the thickness of the meter, this was not possible. To ensure stability and robustness of the test strip drum the round shape and size of the test strip drum could not be changed.

The meter is delivered with preset time and date. A power supply is necessary to retain pre-settings.

Not if the meter is handled as instructed. However, if it is misused (the ejected test strip is not held slanting downwards when drawing up blood or control solution) the optics part can become dirty.

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

Yes, the meter has a re-dosing option within 25 seconds.

The meter has a test button which prevents the system from being switched on inadvertently. Otherwise a test strip would be wasted each time this happens, because switching on the meter with the test button immediately starts the test strip advance mechanism.

Yes, it does. As higher the level of brightness selected, more power is consumed. The default setting is Level 2.

All test strips (including those of our competitors) are moisture-sensitive. The drum contains desiccant which protects the test strips from moisture for 90 days (in all climatic zones). After that time the desiccant is used up and the test strips are exposed to moisture.
They become unusable after just a few days. An additional desiccant protects the test strips in the unopened vial until the printed expiration date.
When a test strip drum is placed in the Accu-Chek Compact Plus meter, the display shows the drum symbol, the flashing bottle, and clock symbol after 90 days. This means that the test strip drum can no longer be used. Legally, the test strips must not be used. If they are, the readings obtained must be used for guidance only.                                      

When the drum compartment cover is opened, a control test is needed to see if the test strips are still useable. The meter registers every opening of the drum compartment cover and the drum symbol and flashing bottle symbol appear in the display. To prevent incorrect results, the quality of each test strip is also checked again before it is used

High energy batteries last at least 1,000 tests or one year. The internal clock uses power irrespective of the number of tests, even when the Accu-Chek Compact Plus blood glucose meter is switched off.
The number of tests may be reduced when the batteries are removed, test frequency is extremely low (1 test per week), and the meter is left unused. The number of tests may be improved where the test frequency is high. Note that outside temperature and the quality of batteries used could also affect the number of tests.

Each battery change is a break in the power supply. This means that the Accu-Chek Compact Plus meter does not know whether or not the drum compartment cover was opened and the test strip drum was changed. In this case the meter assumes, for safety reasons, that the drum compartment cover was open and reads the code again. It accesses the first chamber and if this is empty the meter identifies the test strip drum as having been used.
Another old, used test strip drum could have been inserted during the battery change. That is why, for safety reasons, the meter now prompts the user to carry out a control test.

The barcode reader has an automatic error detection which meets the highest reliability standards. If an error is detected, an error message appears. You should then proceed as described in the instructions and take another test strip drum from the same package to continue with your measurement. All test strip drums produced by Roche Diabetes Care have been tested (and pressure tested) and passed 100 % by video control.

The motor as well as the mechanism has been designed to last for at least 6,000 tests. Additionally, the stability has been successfully tested with a number of drop tests and vibration tests.

Control solutions are individually designed and developed for each Accu-Chek system. The viscosity of the Accu-Chek Compact Plus control solution is higher than for other Accu-Chek control solutions.

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

No, test strip transportation problem is solved by a redesign. Tests showed reliability of the process.

The Gluc-Dor enzyme used has a negligible dependence on the atmospheric oxygen level. For this reason its altitude dependence is also extremely small. Full functionality is guaranteed and tested for up to 4,000 meters.

The readability in bright sunlight is a disadvantage of the OLED. By covering the display with your shadow it is readable again.

  2. Press the red drum release button
  3. Tip the meter forwards so that the old test strip drum drops out
  4. Insert a new drum
  5. Close the drum compartment cover (automatic coding)

4 simple steps for testing blood glucose

  1. Slide and release the Test button to release a test strip
  2. Lance to obtain a blood sample
  3. Hold the meter so the test strip is pointing downwards. Apply your blood sample to the black notch of the test strip. Read the blood glucose result.
  4. Slide and release the Test button to eject the used test strip
