3.2 Micronaire Calibration
Past research and experience with the Micronaire component that is
used in
HVI SPECTRUM
have proven the stability of the instrument.
Therefore, it is recommended that a
routine check
be performed rather
than a
routine calibration
. A calibration should only be completed in
cases of extreme swings in humidity or a malfunction in the unit.
Note:
Due to possible operator error, calibrating the Micronaire on a
routine basis without prior checks (tests) could result in less than
favorable results. Calibration requires a very precise mass (±0.03
grams). If a small amount of the sample is lost or if the sample is not
prepared correctly a miss-calibration can occur.
It is EXTREMELY IMPORTANT to KEEP a RECORD of the
ORIGINAL SETTINGS for future use.
