How to use
Before using the tool for the first time or when changing the battery, you need to check and update the settings.

Blood sugar test
The meter offers 4 measurement modes, General, AC, PC and QC. You can switch between these modes: start with the meter turned off. Insert a test strip to turn the device on. The screen will display a drop symbol that will flash on the display and "Gen". Press the button to switch between General, AC, PC and QC modes.

Beta-ketone test
The meter only offers one “Gen” measurement mode. Start with the meter turned off. Insert a test strip to turn the device on. The screen will display the drop symbol flashing on the display and “Gen”.

Test with control solutions
Control solutions contain a known amount of glucose or beta-ketones that react with the test strips and are used to ensure that the meter and strips are working properly together.
Perform the control solution test when:
- you use the meter for the first time;
- at least once a week to regularly check the test strips and the meter;
- you start using a new bottle of test strips;
- you suspect that the strips or meter are not working properly;
- the blood glucose test results are not consistent with how the patient feels or the results are thought to be inaccurate;
- to practice the test;
- if the meter has been dropped or damaged.
Test strips, control solutions, lancets or sterile lancets may not be included in the kit (please check the contents on the product packaging). They can be purchased separately. Make sure you have all the items you need to perform a blood glucose or beta-ketone test in advance.

It is recommended to test the control solution at room temperature (20-25 °C). Before testing, make sure that the control solutions, meter and test strips are within this specified temperature range.
Insert the test strip into the meter to turn it on. Wait for the device to display the test strip and blood drop symbol.
Press the button to mark the test as a control solution test. When "QC" is displayed, the meter will store the test result in memory under "QC". If you press the button again, "QC" will disappear and the test will no longer be a control solution test. When testing with control solution, you must mark it so that the test result is not confused with the stored blood glucose test results. Otherwise, the blood glucose test results will be mixed with the control solution test results.
Shake the control solution bottle before use. Discard the first drop and apply the second drop to the tip of the bottle cap. Touch the drop to the absorbent hole of the test strip inserted into the meter. Once the confirmation window of the strip is completely filled, the device will begin counting down.
To avoid contaminating the control solution, do not apply it directly to a strip.
After counting down to 0, the control solution test result appears on the display. Compare the result to the range printed on the test strip vial: the result should be within this range. If not, please read the instructions again and repeat the control solution test.
The control solution range printed on the test strip vial is for control solution only. It does not refer to the level of glucose or beta-ketones in your blood.

Blood test
To reduce the risk of infection:
- never share a lancet or finger prick;
- always use a new sterile lancet. Lancets are for single use only;
- avoid using hand lotions, oils, dirt or residue on the lancets and lancing device.

Massaging the puncture site before drawing blood to stimulate blood flow has a significant impact on the blood glucose value obtained. Blood drawn from a site that has not been massaged has a significantly different glucose concentration than blood drawn from a massaged finger.
Before you begin, wash and dry your hands. Select the puncture site on your fingertip. Clean the puncture site with cotton soaked in 70% alcohol and allow to air dry. Massage the puncture site for about 20 seconds before pricking yourself.
Press the tip of the lancing device firmly against the underside of your fingertip. Press the button to prick your finger; a click indicates that the fingerprick is complete. Choose a different fingerprick site each time you test. Repeated pricking of the same site may cause pain and calluses. It is recommended that you discard the first drop of blood.
Insert the test strip into the meter to turn it on. Wait for the device to display the test strip and drop symbol. Select the desired measurement mode by pressing "M".
Use the adjusted lancing device to perform a finger prick. Wipe away the first drop of blood using clean cotton wool. The minimum amount of blood the device requires is 0.5 microliters (mcL) for glucose and 1 mcL for beta-ketones. Gently press the puncture site to obtain another drop of blood. Do not press the puncture site against the test strip. Be careful not to smear the blood sample.
Draw the drop of blood from the absorbent channel of the test strip. The confirmation window should be completely filled if enough sample has been applied. Do not remove your finger until you hear a beep.
If you do not apply a blood sample to the test strip within 3 minutes, the meter will automatically turn off. You must remove and reinsert the test strip to start a new test.
The confirmation window must be filled with blood before the device begins counting down. Never try to add more blood to the test strip after it has already been applied. Discard the used test strip and perform another test with a new strip. If you have trouble filling the confirmation window, please contact your healthcare provider or Customer Service for assistance.
The blood test result will be displayed after the device has counted down to zero. The results will be stored automatically.
Eject the strip by pressing the eject button located on the side. The device will automatically turn off after the strip is ejected.
Used lancets and strips are a biohazard. Please dispose of them carefully according to local regulations.

Maintenance and cleaning
To replace the batteries, make sure the instrument is turned off. Press the edge of the cover and lift it up to remove it. Remove the old batteries and replace them with two new 1.5V AAA alkaline batteries. Close the battery cover. If the batteries are inserted correctly, you will hear a "beep".
Replacing the batteries does not affect the stored test results. As with all small batteries, they should be kept away from children. If swallowed, seek medical attention immediately. Batteries may leak chemicals if unused for an extended period of time. Remove the batteries if you do not intend to use the device for an extended period of time (e.g., 3 months or more).
