Vulcan Series
Measuring the check sample
The Vulcan series instruments are supplied with a check sample and certificate. It is a good
operating practice to measure the check sample every morning before the first actual
measurement. It only takes couple of seconds but measuring the check sample gives the
confidence that the instrument is working according to the specifications.
Measuring a check sample
It is important to measure the check sample with right technique, so the results are
representative:
○
Always store the check sample in the supplied plastic bag to keep it clean.
○
Clean the measurement window before measuring the check sample.
○
Place the check sample on a flat surface.
○
Point the analyzer at the sample. Take the measurement from a fresh surface, not from top
of an old burn mark.
○
Hold the instrument steadily and keep the analyzer nose in direct contact with the check sample.
○
Pull the trigger, wait for the results to appear and read the results from the screen. Then release
the trigger.
○
Compare the results to the certificate. The grade identification should show correctly.
○
Compare the results to previous measurement done with the instrument and the same
check sample.
It is a good practice to keep a log book of the check sample measurements. That way it is easy to
check the data later, if there should be a question of the instrument performance on a specific
day.
