2 Requirements
The following sections describe each requirement in detail.
2.1 Environmental Requirements
Environmental effects such as acoustic noise, floor vibration and room temperature have a signifi-
cant impact on the performance of the Microscope System and the ability to achieve the specified
performance with particular regard to long term and sensitive workflows as well as equipment
safety.
A site survey can be requested from your local ZEISS service representative prior to the installation.
2.1.1 Acoustic Noise
It is recommended that the microscope system is installed and operated in a quiet room. Sound
waves, e.g. vibration of the air caused by air-conditioning and other systems producing acoustic
noise, will affect the Microscope System and may cause image distortion.
The following noise levels meet the specification of a quiet room and consider the potential reso-
nance frequencies of damping tables.
Allowable noise level
31.5 to 120 Hz
less than 55 dB (Z class)
120 to 200 Hz
less than 50 dB (Z class)
200 to 500 Hz
less than 55 dB (Z class)
2.1.2 Air Conditioning and Quality
The following nominal power usage for the Microscope System and possible accessories is shown
in Watts. To maintain a more constant room temperature, the size of the air-conditioning should
be well matched to the size of the room and the heat generated.
The stable air conditioning of the room is critical to achieving stable and repeatable results from
most imaging and analytical systems.
§
The room should remain at the recommended temperature and humidity 24 h per day and 7
days a week.
§
The air conditioning system must NOT be directed at the system and must be of the correct
size to ensure the room temperature is as stable as possible.
§
Use room temperature and humidity monitoring devices to ensure the stability of the room is
maintained.
In the event of the room temperature changing from the nominal value, the Microscope System
can take up to 3 hours to stabilize before it can be used for reliable and stable results on sensitive
experiments.
