3. Running a test
11
 Always store test strips in their original vial with the cap firmly snap
closed. Close the strip vial securely (until you hear a “click”) as soon as
you have removed your test strip. This will protect the remaining strips
in the vial.
 Always store test strips between 2 °C and 8 °C (35.6 °F and 46.4 °F)
 Use a strip within 10 minutes of removing it from the vial.
 Use each test strip only once and discard after use.
 Try to minimize the time between collecting the sample and applying it to
the test strip.
Do not:
 Do not insert a test strip into the strip port more than once. A test strip
that is inserted twice might fail to make a proper electrical contact with
the analyzer.
 Do not bump the test strip or analyzer after you apply the sample or while
the test is in progress.
 Do not use a vial of test strips if the expiration date recorded on the label
has passed. An error will be displayed if an expired strip is used.
 Do not handle a test strip with wet hands because moisture can damage
the strip.
 Do not use a strip that has been dropped or which may have been
contaminated.
 Do not use a strip if it appears damaged in any way.
 Do not shake, stir, aerate or heat a sample prior to testing as these can
all change the measurable free sulfur dioxide levels.
 Do not apply the sample to the test strip until you are prompted to do so
by the “apply sample” message on the analyzer screen.
 Never add more sample to the test strip after the analysis has begun.
