Permeant Sensor Adjustment Test Setup
To calibrate an instrument to a standard reference film or a certified film use the following procedure:
Mocon has available Certified NIST Films that cover the usual testing range. Call MOCON in
NOTE:
the USA at (763) 493-6370 for more information.
Mocon Certified NIST Films, if not damaged, should last for a year. Do not use the film if it is
NOTE:
wrinkled, punctured or contaminated with grease or fingerprints.
Certified films should be stored in a manner that will keep them clean and free from wrinkles.
NOTE:
MOCON Certified NIST traceable films should be stored in the provided case.
MOCON is not responsible for problems resulting from improper calibration or use of an
NOTE:
inadequate transmission rate reference material.
5.
Select a Certified Film that most closely approximates the transmission rate of the film
samples you will be testing.
6.
Unclamp and remove the Test Cell from the instrument.
7.
Mount the Certified Film (or other reference material) in the Test Cell. For information on
mounting films see "Mounting Samples in the Test Cell" on page 5-4.
8.
Replace the test cell and clamp it in place. For information on installing and clamping the
Test Cell see "Loading and Unloading the Test Cell" on page 5-6.
9.
The Calibration Film Test Procedure should be performed using an "Advanced" Test
Method. For information on how to set up an Advanced Test see the instrument Help
System.
10.
Verify the following Instrument Level parameters have been correctly assigned:
Cell Temperature:
Instrument ReZero:
Use of the "Test ID", "Sample ID" and "Material ID" fields is advised to document all of the
NOTE:
relevant information on the specific material used to perform the test.

If using certified films, the test temperature must be 23.0 °C. If
calibrating with another known film, use the temperature at
which the transmission rate for the film was measured.
