Permeant Sensor Calibration 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 for more information at (763) 493-6370.
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.
1. Select a Certified Film or reference film that most closely approximates the transmission rate of
the film samples you will be testing.
2. Unclamp and remove the Test Cartridge from the instrument.
3. Use the 100%RH Film Test Cartridge (P/N 054-271) designed for this instrument.
4. Mount the Certified Film (or reference film sample) in the Test Cell. Refer to Chapter 7 about
how to mount a film sample for 100%RH testing.
5. 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 3-8.
6. 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.
7. Verify the following Instrument Level parameters have been correctly assigned:
Cell Temperature:
Instrument ReZero:
ReZero Frequency:
ReZero Exam Minutes:
NOTE:
Use of the "Test ID", "Sample ID" and "Material ID" fields is advised to document all of the
relevant information on the specific material used to perform the test.
MOCON, Inc.
If using certified films, the test temperature must be 37.8 °C. If
calibrating with another known film, use the temperature at
which the transmission rate for the film was measured.

Set appropriately for the sample being tested. At least 20
minutes is recommended. The test period may need to be
longer depending on the time the film takes to reach
equilibrium.
