2.2.2. Watlow Instrumentation
The Watlow Instrumentation enables environmental testing under both constant conditions and
programmed conditions, referred to as the “constant mode” and the “program mode”
respectively.
Constant Mode
The constant mode maintains the user-set target temperature (& humidity) constant, thus the
name.
Fig. 2.2. Test Conditions in Constant Mode
Program Mode
The program mode changes chamber temperature and humidity according to a user-set
program.
This program is created before testing starts. It contains multiple steps. Each step contains
temperature, humidity and other settings as with the constant mode. Moreover, settings can be
maintained throughout an entire step or changed at the constant rate.
