page 54 to “Constant Temperature (& Humidity) Setup” on page 62 .

6.4.2 Preventing Dew on Test Specimens
Reference: When testing electronic components or similar specimens, it is necessary to keep
dew from forming on specimens. Dew forms when specimen surface temperature
is lower than the dew point of the air inside the chamber. To prevent dew forma-
tion, first warm specimens under temperature-only operations. Start temperature
and humidity test only after specimen surface temperature is the same as the
temperature inside the test area.
