10 Technical Data and Conformity | 10.2 Installation Requirements
ZEISS
Nitrogen
Gaseous dry nitrogen is used to vent the specimen chamber during specimen exchange. The nitro-
gen can be taken either from a gas cylinder or from an in-house supply system.
Parameter
Requirement
Flow rate
Approx. 40 l/min for ventilation of specimen chamber with chamber
door open
Pressure
0.30–0.35 MPa (3.0–3.5 bar)
Quality
4.6 with nitrogen content > 99.996 %
Connection hose
6 mm inside diameter. 10 m are delivered with the microscope.
Compressed Air
Compressed air is used to operate several valves and the auto leveling system. The necessary com-
pressed air can be either generated by a compressor (part no. 345596-0000-000) or taken from a
gas cylinder or from an in-house supply system.
Parameter
Requirement
Typical flow rate
Approx. 12 l/min at 0.6 MPa pressure during air leveling system infla-
tion
Pressure
0.6–0.8 MPa (6–8 bar)
Quality
Oil-free
Connection hose
6 mm inside diameter. 10 m are delivered with the microscope.
Environmental
Requirements
Parameter
Requirement
Ambient tempera-
ture
Appr. 21±4 °C
Stability of ambi-
ent temperature
0.5 °C/h
For long-running
experiments:
Long-term stability
of ambient tem-
perature
2 °C/24 h
Relative humidity
Less than 65 %
Altitude
Max. 2000 m above sea level to guarantee an undisturbed operation
Pollution degree
2
Electrical field
The microscope is a class A device (industrial). The microscope is de-
signed to operate in a controlled electromagnetic environment. This
means that devices with RF transmitters such as mobile phones or
DECT phones must not be used in close proximity.
Vibrations
Up to 10 Hz: less than 5 μm/s
10–60 Hz: less than 10 μm/s
Above 60 Hz: less than 14 μm/s
