5.6 Condensation Control
The optional condensation control feature is for situations in which condensation is undesirable or
detrimental to the product being tested. When enabled, the rate of rise in temperature is limited in
order to allow the humidity control system to strip moisture from the chamber in order to keep the
dewpoint of the air below the product temperature. If the dewpoint of the air were to exceed the
product temperature, moisture could form on the product’s surface.
Figure 5-7 Condensation Control
There are many factors that can affect the performance of the chamber including product placement,
mass of product and air distribution throughout the chamber. The required ramp rate limit will be
affected by these factors. It may take a little trial-and-error to determine what setting is best for your
testing needs.
Ramp Rate Limit: Adjustable ramp rate limit. Valid range is from zero to 10.0°C (18.0°F). Note
that a limit setting of zero will have no limiting effect on rate of rise.
Dewpoint: Read only parameter which displays current dewpoint of the air within the
chamber.
Dewpoint Limit: Read only parameter which displays the maximum dewpoint that can be
maintained without causing condensation on product.
Monitor Mode Selections
The list of selections on the left of the screen is used to define the method of part temperature
monitoring (only one can be selected at a time, i.e., turning on one will turn off the other selections).
Single: Uses single input, i.e., single sensor located on part.
Low: Uses input with the lowest part temperature.
High: Uses input with highest part temperature.
Average: Uses average of all selected part temperature inputs.
Input Selections
The list of selections on the right of the screen is used to select which inputs will be used for
monitoring part temperature. Note that the standard system has only one selection, the product
control loop input. If the EZT-570S is equipped with the input monitor option, the additional inputs will
be listed for selection.
