2.2 Measurement precautions
AE-4022

 Prepare sufficient volumes of samples so that each test strip pad area can be dipped entirely.
 Measure collected samples directly from collection. Do not add any anti-microbial agent or detergent.
Preservatives may affect results and should be evaluated before use.
 Do not expose samples to direct sunlight. Exposure to direct sunlight may change their properties and
prevent correct measurement.
 Sample containing ascorbic acid may give lower measurement results for GLU and BLD than actual
values.
2.2.3 Precautions for handling test strips
 Use only ARKRAY’s test strips designed for the AUTION ELEVEN
The AUTION ELEVEN works with special test strips designed and made by ARKRAY, Inc. Thoroughly
read the test strip package insert and use them by the expiry date.
 Check before use
Do not use any test strips whose expiry date has passed. Do not use any test strips whose pad area
shows signs of discoloration, even if the expiry date has not yet passed. Measurements using such test
strips will give incorrect results.
 Prepare test strips just before measurement
Take out from the bottle only the number of test strips required for measurement. Unused test strips
exposed to the air will absorb moisture or be contaminated with dust or dirt, which will cause incorrect
measurements. After taking out the test strips, immediately close the bottle cap securely.
 Do not touch the test strip pad area
Never touch the test strip pad area. Touching this with bare hands may cause sebum (skin oil) to adhere,
which will cause incorrect measurements.
 Select the type of test strip
Before measurement, select the correct type of test strip to use. Using test strips of a different type from
that which the instrument is set to use will cause incorrect measurement results.
 Do not discard desiccant
Do not discard the desiccant in the bottle before using all the test strips inside. Without the desiccant,
the remaining test strips will absorb moisture from the air, which would change their properties and cause
incorrect measurements.
