Getting started
Before using your meter for the first time, insert batteries in the battery
compartment. See
Changing the batteries
section of this manual.

Coding your meter (Calibration)
Each pack of test strips comes with a memory card that must be
inserted into the meter before any tests are performed.
In addition to recording your result, the memory card programs the
meter to read test strips accurately.
Each memory card has a three-digit number printed on it called
a code number. The code number is also printed on the test strip
container.
Before you insert the memory card the meter will display three bars
and flash the word
code
.
Procedure for coding
Step 1:
Insert memory card
Take the memory card from the pack of test strips and insert it into
the meter.
The meter will sound a chime when the card is correctly
inserted and the coding is completed*.
* If you have the sound turned off, there will be no chime.
Procedure for coding
Step 2:
Check code number
The meter will then display a three-digit code number.
The following is an example only:
Check that the number displayed matches the number printed on
the container of the test strips and memory card.
Example:
In the above case, the screen, the memory card and the
label should all have the code number 829.

Caution:
It is critical that a pack of test strips be used only
with the memory card supplied. The memory cards are not
interchangeable as each has different calibration information.
The memory card carries calibration data only for the pack with
which it is supplied. When the meter is programmed with this
data it is able to give accurate results for that pack only.
If the code number on the screen does not match the code
number on the pack of tests, the meter will give incorrect
readings!
The G5 meter has an LCD that should be checked periodically to
ensure it is showing all segments correctly.
Turn on the meter using the
button and the meter will perform a
screen test by lighting all segments for 3 seconds.
Check that all the segments are functioning correctly as shown
above.
2. Checking the Display
The G5 meter has two memory systems that work automatically and
in conjunction to provide you with a record of your results.
1.
Card Memory
2.
Meter Memory
Why two systems?
The meter has a storage capacity of 250 results. When full, the
oldest results are deleted to make room for new ones. This is
a “first in, first out” system which means results are not stored
permanently.
Conversely, the memory card supplied with each pack of test strips
provides a permanent record of results from a single pack of strips.
4. Memory
1. Card memory
Each new pack of test strips comes with a memory card that will
permanently store the 50 results with time and date.
When a test is performed, the result is automatically stored on the
memory card. Once the pack is finished, you should have 50 test
results stored on the memory card. The memory card stores these
results permanently and it should be kept for future reference. An
extended chime indicates that the memory card is full.
Recalling results from the memory card using the memory
button
With the card inserted, press and hold the
button until ‘C1’
appears, this indicates that the card is being read. When the button
is released, the most recent test result will be displayed. Use the
button again to read ‘C2, 3, 4...’ to a maximum of 50.
Note:
The prefix ‘C’ means card memory.
2. Meter memory
Your meter stores 250 test results with time and date. Each time
a test is performed and a result displayed, the meter automatically
stores the value in memory. If 250 results are already stored, then
the oldest result is deleted to make space for the newest result.
Recalling results from the meter using the memory
button
Remove the memory card
and press the
button. This will
recall a maximum of 250 results in the meter.
When pressing and holding
button, the memory number will
be displayed and when the button is released, the result will be
displayed.
Recalling 7 and 14 day averages
1.
Turn the meter off.
2.
Press and hold the
button until 7d appears
(approximately three seconds).
The result that appears immediately after releasing the
button
is the 7 day average. Press again
and 14d appears, release for
the 14 day average.
Note:
Time and date must be set.

Accuracy
Comparison against capillary whole blood by hexokinase method
produced the following regression:
y(mg/dL) = 1.0307x - 6.4114 R² = 0.9815.
Precision
The repeatability obtained with the blood samples is shown in the
following Table. The table gives the pooled standard deviation and
pooled CV% with 95% confidence intervals for the five levels of
glucose tested (n=100). No outliers were detected and excluded from
data analysis.
At glucose concentrations of 44.7, 96.1, 132, 170 and 276 mg/dL
coefficients of variation (CVs) of 3.7, 3.5, 2.3, 2.8 and 2.1% were
obtained respectively, indicating a high degree of precision. At all
glucose levels tested the coefficient of variation was below 4%.
Sources of interference
Do not carry out a test in direct sunlight. Strong electromagnetic fields
(e.g. mobile phones, microwave ovens) may affect performance.
Betachek G5 will detect this and an error message will be displayed.
