Step-by-step guide
Follow the illustrated sequence below. Each step explains what to do and what to watch for.
01Make sure the CR2032 battery is fitted in the marked +/− direction. Wash with soap and warm water, then dry thoroughly. Set out a fresh strip, your lancing device and a new sterile lancet.
Remember Handle strips with clean, completely dry hands.
02Remove the cap, insert a new lancet, twist off its protective cover and replace the device cap. Set the depth for your skin and pull back the cocking handle until it clicks.
Remember A higher depth number means a deeper puncture. Do not share the device or lancets.
03Take one strip out and close the vial immediately. Insert the contact-bar end fully into the meter, with the front side facing up. Wait for the flashing blood-drop symbol.
Remember The meter turns on automatically when you insert the strip.
04Hold the lancing device firmly against the side of your fingertip and press its release button. Wipe away the first drop and gently form a fresh drop.
Remember Avoid squeezing hard. Let any alcohol used on the skin dry completely first.
05Bring the absorbent opening at the strip tip to the blood drop. Let it draw blood in until the confirmation window is filled and the meter beeps. Keep the strip in place for the 5-second countdown.
Remember Touch the drop with the tip; do not smear blood on the strip or apply it twice.
06Read the result; it is stored automatically. Eject the used strip. Open the lancing-device cap, secure the lancet tip in its protective cover, then eject it into an appropriate sharps container. Wash your hands afterwards.
Remember Use a fresh strip and lancet for every test. Do not leave used supplies exposed.

Insert a fresh compatible strip fully, contact-bar end first. The meter starts automatically. Wait for the flashing blood-drop symbol before applying the sample. If nothing appears, check the CR2032 battery is installed in the marked +/− direction; replace it if depleted.
No. Touch the absorbent opening at the strip tip to the blood drop and let the strip draw it in. Wait until the confirmation window is filled and you hear the beep. Leave the strip inserted for the 5-second countdown. Do not smear blood on top or apply a second sample.
Turn the numbered depth selector on the lancing device. For the five-level device shown, 1–2 is for soft or thin skin, 3 for average skin, and 4–5 for thick or calloused skin. A higher number makes a deeper puncture; it is not a gender setting.
The strip may not be fully inserted, or its sample window may not have filled. Check insertion before sampling. If the strip already has an incomplete blood sample, discard it and repeat with a new strip and a fresh drop; do not add more blood to the used strip.
The meter automatically stores up to 500 readings. With it off, briefly press M to show the latest result, then briefly press M again to review earlier readings. Keep any separate log your healthcare professional has asked you to maintain.
