RECALIBRATION

improperly. Recalibration insures the instrument is clean and free
from debris.
►Recalibration maintains your LIFETIME WARRANTY!
Sending your unit for recalibration is easy and inexpensive. Recalibrations
are usually shipped within ve days of receipt, so it’s fast too.
Please keep the original box to return your Alicat instrument for recalibration.
For more information regarding recalibration see page 51.
