Setting the Chamber Temperature via Serial Port (RS-232)

Refer to the section titled “Serial Port Communications” on the next page.

Installing the Permeation Device(s)

1. Withthetoolprovided,rotatethepanellockscrew90°counterclockwise.

2. Remove the front panel oven cover to access the 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.

3. Unscrew the chamber cap with the tool provided.

4. Addorremovethepermeationdevice(s)withthesuppliedforcepsorother

tool appropriate to the job..

5. Secure the chamber cap with the tool provided.

6. Run a pressure/decay test to make sure that the chamber cap is leak tight.

7. Reinstall the front panel assembly and rotate the panel lock screw

90°clockwise.

8. Allowonehourforequilibration.Refertotheseparateinstructionsaccom-

panying the permeation tube to make sure that the selected temperature is

compatible with the permeation tube being used.

The Dynacalibrator is ready to be put into service.
