Operation and control
5.8.7 Example setting programming mode
For the TTC temperature test chamber there is no programming of humidity.
On Monday at 8.00, the test chamber should heat up to 50 °C as quickly as possible, with a
fan speed of 40 %, and reach a relative humidity of 70 % rh. Once the temperature and hu-
midity have been reached, the test chamber should retain the setpoint values for 45 minutes
and then cool down within one hour to a humidity of 50 % rh and 37 °C ( Fig. 26 ).

Before programming ramp sequences, especially complicated ones, it is recommended
that you prepare a similar plan so that you enter the required ramp commands correctly,
as described below. For the sake of retaining an overview, it is recommended that you
programme large programmes graphically on the PC.
