3.2 STEP A•
Bring the chamber up to the departure temperature value of 20°C.
gradient: 1°C/min
gradient: 2%/min
3.2 HOW TO SET A CONTROLLED SLOPE
- Setting of a controlled temperature slope (Ex-
ample 20÷35°C) with an average gradient of
1°C per minute and 60% relative humidity
- Setting of a humidity from 60 to 90% with a
gradient of 2% per minute
(in order to calculate the average gradient, that is
the temperature rise or descent speed, please
refer to the technical data contained in the cham-
ber instruction handbook).

Operations:
3.2.1 Step A: follow the same procedure de-
scribed in paragraph 3.1 so that the departure
temperature in the chamber reaches 20°C in
manual mode.
3.2.2 Step B: set a temperature slope from 20°C
to to 35°C and follow a slope with a gradient of
1°C/min.
The machine will reach the set temperature and
humidity and will then maintain these values;
3.2.3 Step C: keep a constant temperature
(35°C) and set the controlled humidity value
(60÷90%) RH with a gradient of 2% per minute.
NB: if a mistaken gradient value is set, the ma-
chine will not follow the set slope but will still reach
the final temperature and humidity.
We advise you not to carry out controlled tem-
perature and humidity slopes (with a gradient)
at the same time; in fact, the humidity slope
would not be sufficiently controlled.
When you carry out a humidity slope, make
sure that the temperature is kept constant.
