7.1
AIM OF THE MACHINE
The machine has been designed to carry out temperature and humidity tests on components and electrical equipment.
The machine is also suitable for temperature and humidity tests on industrial and pharmaceutical products (CHAL-
LENGE -E series).
Before placing any object whatsoever inside the chamber, make sure that the object itself will not be damaged by the
test temperature.
For further information, please refer to chapter 3 entitled “Technical specifications”.
7.2
MACHINE END-USE
The machine has been designed to be used in companies and must only treat the objects mentioned in paragraph 7.1.
Before treating different materials from those indicated in paragraph 7.1, please contact the manufacturer to obtain a
specific authorization.
7.3
OPERATOR
No special technical knowledge is needed to use this machine.
The operator should read this handbook carefully. However, experience with the use of electrical and electronic
equipment would be preferable.
Special attention must be paid to the temperatures which can be reached inside the test chamber. The
temperature range for the equipment given in this handbook ranges from +180
°
C to-20
°
C or -40
°
C or -70
°
C.
Before opening the door to handle the tests, set the equipment to values close to ambient temperature and
give enough time for temperature to stabilize itself; wear special gloves that resist at high/low temperatures.
