Installing the Permeation Device(s)
1. Turn off the power switch.
2. With the tool provided, rotate the panel lock screw 90° counterclockwise.
3. Gently pull the front panel assembly out.
CAUTION: The permeation chamber cap may be warm to
touch. If the calibrator has been in use, avoid exposure
to gas vapors while opening the chamber cap by using
appropriate mitigation and personal protection equipment.
4. Unscrew the chamber cap with the tool provided.
5. Add or remove the permeation device(s) with the supplied forceps or
other tool appropriate to the job.
6. Secure the chamber cap with the tool provided.
7. Run a pressure/decay test to make sure that the chamber cap is leak
tight.
8. Reinstall the front panel assembly and rotate the panel lock screw 90°
clockwise.
9. Turn on the power switch and allow one hour for equilibration.
Refer to the separate instructions accompanying the permeation tube to
make sure that the selected temperature is compatible with the permeation
tube being used.
Important Permeation Device Considerations
• If more than one tube is to be used in the oven at the same time, order all
the tubes with permeation rates given at the same temperature.
• Certified permeation devices should be used only at the temperature
specified on the certificate.
• Using any permeation device beyond its recommended temperature
range could result in the destruction of the device by explosion and/
or changes in the membrane characteristics. If in doubt, contact VICI
Metronics or their authorized representative with the part number of the
device to determine its maximum temperature limit.
