For calibration points found in
1. Fully open the vent valve by turning it counter-clockwise.
CAUTION! Make the following adjustments slowly, being careful not to overshoot the target value. NEVER
ALLOW THE SYSTEM TO GO TO A VALUE WETTER THAN THE TARGET VALUE. If you overshoot a
value in the wetter direction, you will have to allow the system to equilibrate (dry down) again
before you can proceed.
2. In , look below the body of the table for Notes 1 and 2. Adjust both the valves on the

After stabilizing, the system output will be at the selected dew/frost point temperature and it is ready for use. The
stabilization period depends on the dew/frost point temperature you are using. In general, the following times are
required:
•
For dew/frost point temperatures of -60°C (-76°F) and drier, allow 2 hours
•
For dew/frost point temperatures of -60°C (-76°F) to -40°C (-40°F), allow 1 hour
•
For dew/frost point temperatures of -40°C (-40°F) and wetter, allow 30 minutes
After you have completed the calibration or other calibrated moisture operation at this dew/frost point temperature,
either shut down the system (see "System Shutdown" on page 12), or repeat the steps in this section for the next
calibration point.
