APPLICATION SOFTWARE
To avoid a long period of time between switching off the S904D and the end of the
S904D control program there is a
default after completion
button.
Activation of this button creates an additional setpoint of ±20°C and 50%RH after the
program is
fi
nished. (These values will not be logged).
This additional setpoint remains active until the S904D is switched off.
The orange light will come on.
Example of a test program :
1
stabilize the chamber for 30 minutes at 20°C and 50%RH.
(assuming the S904D starts at ambient temperature and
humidity ±20°C/±50%RH).
2
go in 1 hour to 30°C and 20%RH, and stabilize for 1.5 hours.
3
go in 1 hour to 40°C and 20%RH, and stabilize for 2 hours.
4
go in 0.5 hours to 48°C and 60%RH, and stabilize for 2.5 hours.
5
go in 1.5 hours to 20°C and 50%RH, and stabilize for 0.5 hours.
