CALIBRATION
Calibrations are an important part of maintaining accuracy.
4.1 FACTORY CALIBRATION
The Model 480L is calibrated to NIST traceable standards on the 0-1 ppm range
prior to shipment. A calibration certificate for your instrument can be purchased
from Teledyne API if required. Teledyne API also recommends that the Model
480L be re-calibrated once a year. Teledyne API can provide NIST traceable
calibration services at our factory or on-site. Please contact our Technical Support
department for details on these services.
4.2 ZERO, SPAN, AND FLOW CALIBRATIONS
A zero calibration can be easily performed in the field, and Teledyne API
recommends that this be done at least annually. See Section 5.2.3.2 for details on
performing a zero calibration, Section 5.2.3.3 for span calibration, and
Section 5.2.3.4 for flow calibration.
