AMI FACTORY CONFIGURATION AND CALIBRATION
Every
MODEL 4010LX
Moisture Analyzer is rigorously tested and calibrated at the factory
over the entire measurement, temperature, and pressure ranges, using NIST traceable gases
and sophisticated mass flow controllers within a temperature chamber. The performance of the
Analyzer during the 30+ hours of testing and calibration is validated, using NIST traceable
master analyzers, which are further validated using chilled mirrors. The master calibration
variables, which are specific to each analyzer, are permanently loaded into the Analyzer’s
firmware. During the validation, performance testing of all results across all temperatures must
meet a 1% or better accuracy specification prior to passing.
FIELD PERFORMANCE VALIDATION
This factory calibration performed by AMI and the inherent stability of the ratio metric WMTDL
measurement result in an Analyzer that will hold its calibration for many years. A customer
may want to periodically verify the accuracy of the
MODEL 4010LX
using their own NIST
traceable calibration gas, but it is important to follow AMI's specific steps so that errors are not
introduced. You can read AMI’s recommendations for field validation of a
MODEL 4010LX
in appendix A.
