5. Turn off the power switch and wait 15-20 minutes for the chamber to cool.
6. Turn on the heater power switch and set the chamber operating temperature.
When PFAIL occurs, the Dynacalibrator must be turned off
long enough for the chamber to cool before the power is
turned back on.
Installing the Permeation Device(s)
1. Reduce the temperature setpoint for the permeation chamber to 30°C. Allow
time for the chamber to cool to this temperature, which will be indicated by
the status indicator changing from red (not ready) to green (ready).
2. Turn off the main power switch on the front panel.
3. With the tool provided, rotate the panel lock screw 90° counterclockwise.
4. Remove the front panel oven cover to access the permeation chamber cap.
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.
5. Unscrew the chamber cap with the tool provided.
6. Add or remove the permeation device(s) with the supplied forceps or other
tool appropriate to the job..
7. Secure the chamber cap with the tool provided.
8. Run a pressure/decay test to make sure that the chamber cap is leak tight.
9. Reinstall the front panel assembly and rotate the panel lock screw 90° clockwise.
10. Turn on the power switch.
11. Enter the new permeation device parameters (refer to "Tubes Screen" on page
14). and the new temperature set point for the chamber (refer to "Setting the
Chamber Temperature" on page 10).
Refer to the device-specific instructions accompanying the permeation tube
to ensure that the temperature entered is a safe operating temperture.
12. To establish the desired concentration, set flows from the Manual screen or
set concentration from the Auto screen (page 16).
Allow time for equilibration. When the status indicator changes from red (not ready)
to green (ready), equilibration has been achieved and the Dynacalibrator is ready
to be put into service.
