MANUAL OPERATION

In order to make the following instructions easier to understand, examples with the relevant values will be given.
Operations that can be carried out in manual mode:
3.1

HOW TO SET A VALUE

- Temperature value setting (e.g.
80°C)
- Humidity value setting (e.g. 70%)
The machine reaches the set value, at
maximum speed, both when it rises
and when it descends.
Once the value has been reached, the
machine will maintain this value.
3.1 HOW TO SET A VALUE
- How to set a temperature value (e.g. 80°C)
- How to set a humidity value (e.g. 70%)
• Switch on the machine as described in paragraph 2.4.

3.2 HOW TO SET A CONTROLLED SLOPE
- Controlled temperature slope setting (Example 20 ÷ 35°C) with an
average gradient of 1°C per minute and 60% relative humidity.
- Humidity setting 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 chamber
instruction handbook).
Steps to be carried out:
3.2.1 Step A: follow the same procedure described in paragraph 3.1 so that
the departure temperature in the chamber reaches 20°C in manual mode.
3.2.2 Step B: set the final value to 35°C and follow a slope with a gradient
of 1°C/min. and 60% relative humidity.
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 RH
humidity cycle (60÷90%) with a gradient of 2% per minute.
NB: if a mistaken gradient value is set, the machine will not follow the set
slope but will still reach the final temperature and humidity.
