Operating Conditions - NT-MDT NTEGRA Spectra Instruction Manual

1.5. Operating Conditions

To provide for the normal operation of the device, it is recommended to observe the
following conditions:
−
environment temperature:
−
temperature drift less than 1 °C per hour;
− relative humidity at +25 °С
−
range of purity
−
vibration amplitude
in the band 1 ÷ 1000 Hz
−
atmospheric pressure
−
the work area should be supplied with a protective grounding circuitry and with
grounded electric mains (110/220 V);
−
electric mains:
- voltage
- frequency
−
the room should be protected from mechanical vibrations and acoustic noises, either
internal or external;
−
vibration criterion VC-C, 12.5 µm/s (one-third octave band criterion);
−
the device should be protected from the direct sun radiation impact;
−
to provide solid stability against vibrations, SPM modules should be placed on
leveling floor with marble covering alongside bearing components of the building
(pillows, beams etc.);
(25 ± 10) °C;
less than (65 ± 15) %;
7 – 8 (by ISO 14644-1);
less 0.5 µm;
760 ± 25 mm Hg;
110/220 V (+10 % / –15 %),
50/60 Hz;
