of whether the microscope is in operation or
switched off) 22 ± 3 °C

Dust can cause erratic errors or possibly irreversible damage to electronic devices. Care should be
taken that the site is as dust free as possible.
2.1.2.1 Pollution Degrees
IEC 61010-1 specifies different types of pollution environments.
Pollution De-
gree Description
1 No pollution or only dry, nonconductive pollution occurs. The pollution has
no influence. Example: A circuit in a hermetically sealed box (such as an IC
chip). No air can come into the box to bring condensation or conductive
particles.
2 Only nonconductive pollution occurs. Occasionally, temporary conductivity
caused by condensation is to be expected. Example: A circuit used in an of-
fice environment. The circuitry inside a computer would fall in this cate-
gory.
3 Conductive pollution occurs, or dry nonconductive pollution occurs that
becomes conductive due to condensation that is to be expected. Example:
Circuitry that is exposed to outside air, but will not be in contact with pre-
cipitation. A garage door opener would fall under this category. Note: Al-
though the IEC has defined this pollution degree in other documents,
IEC 61010-1 does not cover Pollution Degree 3.
4 The pollution generates persistent conductivity caused by conductive dust
or by rain or snow. Example: An exposed outdoor control box for a water
pump. Note: Although the IEC has defined this pollution degree in other
documents, IEC 61010-1 does not cover Pollution Degree 4.
2.1.3 Electromagnetic Compatibility
The Microscope System is suitable for laboratory and industrial premises but less suitable for do-
mestic premises where the EMC could interfere with nearby domestic appliances such as land line
phones and radios. The system can cause minimal electrical and radio interference as detailed by
its classification as a CISPR 11 / DIN EN 55011 / class A system according to DIN EN 61326-1.
