Getting to know your device
The GL50 blood glucose measuring system is intended for fast and simple blood glucose measurement
of fresh whole-blood samples, either for self-testing or in a clinical environment by trained personnel.
It enables you to measure your blood glucose quickly and easily, store the measured values and
display the average of all measured values, thereby providing optimum assistance for monitoring your
diabetes. Testing is exclusively performed externally (IVD).
The backlit display shows measured values clearly. The user-friendly design with handy test strips,
and simple controls with just a small number of buttons guarantee clear yet reliable measurements.
The device can be directly connected to a PC using the integrated USB connection. You can evaluate
the measured values on your PC using special software (in English and German language) and use
the results to monitor your blood glucose values.

2 warninGs and safety notes
Risk of infection
All components of the blood glucose monitor and its accessories may come into contact
with human blood and are therefore a possible source of infection.
Warning
• Blood glucose values are displayed in mg/dL or mmol/L. You risk damaging your health if
you measure your blood glucose value using a unit of measurement with which you are not
familiar, misinterpret the values and consequently take incorrect measures. Therefore, please
ensure that this monitor displays a unit of measurement with which you are familiar. The unit
of measurement accompanies each blood glucose value. Please contact Customer Services
if the device displays the incorrect unit of measurement.
• When using the monitor for multiple persons, observe the generally applicable regulations regarding
disinfection, safety and contamination.
• Medical carers and others who use this system on multiple patients must be aware that all products
or objects that come into contact with human blood must be handled as though they could transfer
pathogens, even after cleaning.
• The lancing device is suitable for self-testing. Do not share the lancing device or lancet needles with
others or among multiple patients (risk of infection!).
• Use a new, sterile lancet needle for each blood sample (for single use only).
General notes
Warning
Do not use the device in the vicinity of strong electromagnetic fields and keep it away from radio
systems or mobile telephones.
Measuring the blood glucose content
Warning
• The measurements taken by you are for your information only – they are not a substitute for a medical
examination! Consult your GP regularly regarding your measured values. Never alter the procedures
prescribed by your GP of your own accord.
• The Beurer GL50 monitor provides a simple way of monitoring your own blood glucose levels,
however you may need to obtain information on how to use the system from your healthcare
professional (for example, your GP, chemist or diabetes consultant). Only proper use guarantees
exact measurements.
• This device may be used by people with reduced mental capabilities provided that they are supervised
or have been instructed on how to use the device safely and are fully aware of the consequent risks
of use.
• A lack of water, high fluid loss – for example from perspiration, frequent passing of water – severe
hypotension (low blood pressure), shock or hyperosmolar hyperglycaemic non-ketotic coma (HHNKC)
may lead to incorrect measurements.

8 Beurer GL50
• A haematocrit value (proportion of red blood cells) between 30% and 55% has no significant influence
on the measurement results.
• A very high or low haematocrit value (proportion of red blood cells) may lead to incorrect
measurements. In the event of a very high haematocrit value (above 55%), the displayed blood
glucose value may be too low; in the event of a very low haematocrit value (below 30%), it may be
too high. Consult your GP if you do not know your haematocrit value.
• Do not use the test strips to measure blood glucose values of newborns.
• Do not use NaF or potassium oxalate anticoagulants to prepare for venous blood samples.
• Do not test any severely ill patients using this device.
• Use fresh capillary whole blood only. Do not use serum or plasma.
• Use capillary blood without squeezing the penetration area. Squeezing the area causes the blood
to be diluted with tissue fluid and this may lead to an incorrect measurement.
• Do not use the test strips at altitudes above 7,010 metres.
• Very high levels of humidity may influence the test results. Relative humidity of more than 90% may
lead to inaccurate results.
Note
T he Beurer GL50 measuring system is intended for measuring capillary and venous whole blood.
Storage and maintenance
Warning
• Store the monitor and its accessories out of the reach of small children and pets. Small parts such
as lancet needles, batteries or test strips may be life-threatening if swallowed. If swallowed, seek
medical attention immediately.
• The test strip box contains desiccant, which may irritate the skin or eyes when inhaled or swallowed.
Keep the box out of the reach of children.
The monitor is made from precision and electronic components. The accuracy of the measured values
and service life of the device depend on its careful handling:
• Protect the device and its accessories from impact, humidity, dirt, significant temperature fluctuations
and direct sunlight. Do not store the device, test strips or control solution in your vehicle, in the
bathroom or in a cooling appliance.
• Do not drop the device.
Batteries / Saving measured values
Notes on handling batteries
• If your skin or eyes come into contact with battery fluid, rinse the aected areas with water and seek
medical assistance.
• Choking hazard! Small children may swallow and choke on batteries. Store batteries out of the
reach of small children.
• Observe the plus (+) and minus (-) polarity signs.
• If a battery has leaked, put on protective gloves and clean the battery compartment with a dry cloth.
• Protect the batteries from excessive heat.

Beurer GL50 9
• Risk of explosion! Do not throw batteries into a fire.
• Do not charge or short-circuit batteries.
• If the device is not to be used for a relatively long period, take the batteries out of the battery
compartment.
• Use identical or equivalent battery types together only.
• Always replace all batteries at the same time.
• Do not use rechargeable batteries!
• Do not disassemble, open or crush the batteries.
Note
• The stored blood glucose values are retained when the batteries are replaced. If applicable, the date
and time must be reset after replacing the batteries.
• Use lithium-ion batteries only.
Repairs
Note
• Do not open the device. Failure to comply with this instruction will void the warranty.
• Do not repair the device yourself. Proper operation can no longer be guaranteed in this case.
• Please contact Customer Services for repairs.
Disposal
Warning
• It is essential to comply with the generally applicable safety precautions for handling blood when
disposing of materials from the monitor. Dispose of all blood samples and materials with which you
or your patients come into contact correctly, in order to prevent injury and infection of other persons.
• After use, dispose of test strips and lancets in a puncture-proof container.
Note
Batteries must not be disposed of with household waste. As a consumer, you are required by law to
recycle used batteries. You can recycle your old batteries at public collection points in your community
or wherever batteries of the relevant type are sold.
