How to Use the Beurer GL 48

Preparation: Wash your hands thoroughly with soap and warm water. Dry completely before testing. Insert a CR2032 battery if this is your first use.

Basic Testing Steps:

1. Insert a test strip into the illuminated insertion slot until you hear a click.
2. Use the included LD 04 lancing device to obtain a small blood sample from your fingertip.
3. Apply the blood drop to the test strip's designated area.
4. The device will count down for approximately 5 seconds.
5. Your blood glucose measurement will display on the screen.
6. Mark your measurement (before eating, after eating, or general) using the device buttons.
7. The device will automatically eject the used test strip for hygienic disposal.

Interpreting Your Results: The colored target scale beneath the display shows whether your reading falls within the normal range. The device also provides a ketone warning indicator if needed.

Data Management: Connect your device to a computer using the included USB cable to transfer measurements to beurer HealthManager Pro or compatible software for detailed analysis.

Initial use

Removing the battery insulation strips, replacing the batteries

• Two batteries are included in delivery of the blood glucose monitor. These have already been inserted into the battery compartment.
• Remove the insulation strip before initial use.
• Remove the battery compartment lid on the underside of the device.
• When replacing the batteries, remove all batteries. If necessary, reset the date and time.
• Insert two new CR2032 3 V batteries. Make sure that the batteries are inserted the correct way round in accordance with the markings. See the graphic in the battery compartment.
• Close the battery compartment lid again carefully.

Making and changing basic settings

Remove the batteries and reinsert them. Alternatively, press the SET button. The year display flashes.

Setting the date and time

• You must set the date and time. Otherwise, you will not be able to save your measured values correctly with a date and time and access them again later.
• The time is displayed in the 24-hour format.
• Set the year (calendar to 2099) by pressing the “+” or “–” button. Confirm using the SET button.
• The day display flashes.
• Proceed as described above for the month, day, hour, and minute.

Setting the target scale

You can set a normal range for your blood glucose measuring results with the target scale. After a measurement, a bar in the display will point at the colour-coded target scale beneath the display.

• The bar is in the red area = the measurement value is below the set target range.
• The bar is in the green area = measurement value is within the set target range.
• The bar is in the yellow area = measurement value is above the set target range.
• Set the lower limit of your target range (Lo tAr) by pressing the +/– button. Confirm using the SET button.
• Set the upper limit of your target range (Hi tAr) by pressing the +/– button. Confirm using the SET button.
• The corresponding symbols are displayed.

Switching the acoustic signal on/off

• To switch the acoustic signal on/off, press the “+” or “–” button. The corresponding symbols indicate whether the acoustic signal is switched on or off. 
• Confirm using the SET button.
• The measuring device is now ready for use.

Evaluating measured blood glucose values

Your blood glucose monitor can process measured values between 20 and 630 mg/dL (1.1 and 35.0 mmol/L). The “LO” warning is displayed for measured values below 20 mg/dL (1.1 mmol/L). For measured values above 250 mg/dL (13.9 mmol/L), a ketone warning is also displayed. The “HI” warning is displayed for measured values above 630 mg/dL (35.0 mmol/L).

Functional check using control solution

The control solution is used to test the entire blood glucose measuring system. This helps to determine whether the measuring device and the test strips are working optimally together and whether the test is being performed correctly.Perform the control solution test if you suspect that the measuring device and/or the test strips could be faulty or if you have repeatedly measured unusual blood glucose values. Also test the measuring device if it has been dropped or is damaged. The control solution is available separately. For the control solution test, please observe the additional notes in the instructions for use for the control solution.

Cleaning

• Only clean the device when it is switched off.
• Clean the surface of the device using a soft, slightly damp cloth (water or a mild cleaning solution).
• Dry the device using a lint-free cloth.
• Make sure that moisture does not enter the test strip insertion slot. Do not spray cleaning agent directly on the device. Do not submerge the device in water or any other fluids and make sure that no fluids can get into the device.

Disinfection

Please comply with the generally applicable guidelines on disinfection when using the device on different persons. Do not submerge the device in disinfection solutions or any other fluids and make sure that no fluids can enter the device.

Customer Experience & Reviews

Users consistently praise the Beurer Blood Glucose Monitor GL 48 for its reliability and ease of use. The large, illuminated display receives particular appreciation from users with vision difficulties, making readings immediately clear without squinting[3]. Customers frequently mention the device's quick 5-second measurement time, which fits conveniently into daily routines.

The minimal blood sample requirement (0.5 microliters) is highlighted as a significant advantage, as it reduces testing discomfort compared to older glucose monitors. Users value the colored target scale feature, which provides instant visual feedback without requiring complex interpretation.

Common praise includes the comprehensive starter set, which eliminates the need for immediate additional purchases, and the USB data transfer capability that enables detailed trend analysis with compatible software. The device's accuracy has been verified through clinical testing, giving users confidence in their results.
