11.2 Calibration
As a quality assurance measure, Sierra recommends annual calibration of all measurement instruments. However, how often you have your
Cal=Trak calibrated is an internal quality control decision. The determining factors are whether the unit passes the internal leak test, quality
system requirements if applicable, and the conditions in which the unit is used. Units used in a laboratory setting may require calibration
less frequently than a unit that is used in a manufacturing environment. The annual calibration program is an elective and is therefore not
included as a warranty item. Expedited “RUSH” turnaround service is also available at an additional cost. Please contact the factory for
more information on available calibration services and pricing.
