MONITORING SYSTEM

OWNER’S BOOKLET

TD-4287

Dear owner of GlucoRx Nexus mini Blood Glucose Monitoring System,
The system consists of three main products: the meter, test strips and control solution. These
products have been designed, tested, and proven to work together as a system to produce
accurate blood glucose test results. Only use GlucoRx Nexus test strips and control solutions
with the GlucoRx Nexus mini TD-4287 Blood Glucose Monitoring System.

Intended Use

This system is intended for external use (in vitro diagnostic use) only. It is used for the
quantitative measurement of glucose in samples of fresh capillary whole blood taken from
the palm, forearm, or fingers. It is not intended to diagnose or screen for diabetes mellitus, or
to be used on newborn babies.

Professionals may test with capillary and venous blood sample; home use is limited to
capillary whole blood testing.

This system provides you with plasma equivalent results.

The measurement unit used for indicating the concentration of blood or plasma glucose can
either have a weight dimension (mg/dL) or a molarity (mmol/L). The approximate calculation
rule for conversion of mg/dL in mmol/L is:

For example;

1) 120 mg/dL ÷ 18 = 6.6 mmol/L

2) 7.2 mmol/L x 18 = 129 mg/dL approximately.

Our control solutions contain a known amount of glucose that reacts with test strips. By
comparing the result of your control solution test with the expected range printed on the
test strip vial label, you can check that the meter and the test strips are working together as
a system and that you are performing the test correctly. It is very important that you perform
this simple check routinely to make sure you get accurate results.

HOW TO PERFORM A CONTROL SOLUTION TEST

STEP1. Insert test strip

Insert a test strip into the test slot with the contact bars end first and facing up. (Contact bars
must be inserted all the way into the meter or you may get an inaccurate test result.) The
meter turns on automatically and displays the following in sequence:

When the “ “ symbol appears on the display, press Main button and “QC” will appear on the
display. When the “QC” sign is displayed, the meter will not store your test result in the
memory. If you decide not to perform a control solution test, press Main button again and
the “QC” sign will disappear.

If the confirmation window is not filled completely before the meter begins to count down,
do not add more blood to the test strip. Discard the test strip and start again. If you have
trouble filling the test strip, please call GlucoRx Customer Services on 01483-755133 for
assistance.

Gently apply the drop of blood to the absorbent hole of the test strip at a titled angle.
Confirmation window should be completely filled if enough blood sample has been
applied. Do NOT remove your finger until you hear a beep sound or a count down starts.

If you do not apply a blood sample within 2 minutes, the meter will turn itself off. You
must remove the test strip and insert it back into the meter to restart the test.

NOTE

STEP 2. Setting the time format.

Press Main button to select the desired time format -- 12h or 24h. Press SET.

With the hour flashing, press Main button until the correct
hour appears. Press SET.
With the minute flashing, press Main button until the correct
minute appears. Press SET.

STEP 3. Set the hour and minute

STEP 4. Setting the buzzer beep

1. Start with the meter switched off. Insert a test strip to turn on the meter. The screen will

Your system measures the amount of sugar (glucose) in whole blood. Blood is applied to the
absorbent hole on the test strip and is automatically drawn into the reaction cell where the
reaction takes place.

The test strip consists of the following parts:

Contact Bars

Insert this end of the test strip into the meter.
Push it in firmly until it will go no further.

Test Strip Handle

Hold this part to insert the test strip into the slot.

Absorbent Hole

Apply a drop of blood here.
The blood will be automatically absorbed.

Confirmation Window

This is where you confirm if enough blood has been
applied to the absorbent hole in the strip.

GlucoRx Nexus TEST STRIPS

STEP 1. Set the date

Start with the meter off (no test strip inserted). Press SET.

With the year flashing, press Main button until the correct
year appears. Press SET.

With the month flashing, press Main button until the correct
month appears. Press SET.

With the day flashing, press Main button until the correct

SETTING THE METER

STEP 2. Apply control solution

STEP 3. Read and compare the results

Shake the control solution vial thoroughly before use.
Squeeze out a drop and wipe it off, then squeeze out another
drop and place it on the tip of the vial cap. Hold the meter to
move the absorbent hole of the test strip to touch the drop.
Once the confirmation window fills completely, the meter
will begin counting down. To avoid contaminating the
control solution, do not directly apply control solution onto a
strip.

After the meter counts to 0, the result of the control solution
test will appear. Compare the result with range printed on the
test strip vial. The result should fall within this range.

Out-of-range results

If you continue to have test results falling outside the range printed on the test strip vial,
the meter and strips may not be working properly. Do NOT test your blood. Contact
GlucoRx Customer Services on 01483-755133.

Every time you perform a control solution test you must enter “QC” test mode so that the
test result will not be stored in the meter memory.

CAUTION

STEP 3. Apply blood sample

Wipe the first drop off and obtain a drop of blood of at least 0.5 µL using the GlucoRx lancing
device. Use the clear cap for sites other than fingers and refer to the strip package insert for
more details.

Preparing the Lancing Device for Blood Testing

Please follow the instructions in the lancing device insert for collecting a blood sample.
Never share a lancet of the lancing device. GlucoRx Lancing device is for self-use only.

STEP 1. Insert the test strip to turn on the meter
