1.5. Operating Conditions

To provide for the normal operation of the device, it is recommended to observe the

following conditions:

− environment temperature: (25 ± 10) °C;

− temperature drift less than 1 °C per hour;

− relative humidity at +25 °С less than (65 ± 15) %;

− range of purity 7 – 8 (by ISO 14644-1);

− vibration amplitude

in the band 1 ÷ 1000 Hz less 0.5 µm;

− atmospheric pressure 760 ± 25 mm Hg;

− the work area should be supplied with a protective grounding circuitry and with

grounded electric mains (110/220 V);

− electric mains:

- voltage 110/220 V (+10 % / –15 %),

- frequency 50/60 Hz;

− 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 self-

leveling floor with marble covering alongside bearing components of the building

(pillows, beams etc.);
