Light Exposure

Standard Fluorescent Lighting @ 150 ft. candles (1614 LUX) maximum intensity.
13.4 Installation Category: 2.0
Installation category (overvoltage category) defines the level of transient overvoltage, which the instrument
is designed to withstand safely. It depends on the nature of the electricity supply and its overvoltage
protection means. For example, in CAT II, which is the category used for instruments in installations
supplied from a supply comparable to public mains such as hospital and research laboratories and most
industrial laboratories, the expected transient overvoltage is 2500V for a 230V supply and 1500V for a
120V supply.
13.5

Pollution Degree: 2.0

Pollution degree describes the amount of conductive pollution present in the operating environment.
Pollution degree 2 assumes that normally only non-conductive pollution such as dust occurs with the
exception of occasional conductivity caused by condensation.
13.6 Chemical Exposure
Chemical exposure should be limited to antibacterial materials used for cleaning and disinfecting.
Chlorinated and Halogen materials are not recommended for use on stainless steel surfaces. Chamber
decontamination can be accomplished by paraformaldehyde, vapor phased Hydrogen Peroxide or Ethylene
Oxide without degradation of cabinet materials.
13.7 EMC Performance (classified for light industrial)
European Standard EN 61000-3-2 (1995) (+A14: 2000) Electromagnetic Compatibility Limits for
Harmonic Current Emissions (equipment input current < 16 Amps per phase).
European Standard EN 61000-3-3 (1995) Electromagnetic Compatibility - limitation of voltage
fluctuations and flicker in low-voltage supply systems for equipment with rated current < 16 Amps.
European Standard EN 61326-1 (1997) (+Amendment A1, 1998) Electrical Equipment for Measurement,
Control, and Laboratory Use - EMC Requirements.
(Note: The EMC performance requirements are generated within the product enclosure. The enclosure
will be all metal grounded to earth. In addition, the membrane front panel will also include a ground plane
for maximum protection and an electrostatic shield.
