Installation

Operating Environment

You can use the detector in normal laboratory and cold room environments.
The factors described below will influence the performance of your detector.

Temperature

Changes in ambient temperature can produce noticeable output variations, especially at
higher sensitivities.
Avoid areas which are in direct sunlight for part of the day and those which are subject
to draft; for example, do not place the detector near an open window or doorway.

Contaminants

Smoke, vapors, and acid fumes can cause baseline drift and noise.

Ventilation

You must allow at least 4 inches (10 cm) of clearance behind the detector to permit
exhaust from the cooling fan to escape. Also, do not block the ventilation holes on the
bottom of the detector.

Condensation

The detector has two power controls:
• the front panel LAMP ON/OFF key
• the rear panel MAINS switch
To prevent condensation on optical surfaces, always leave the MAINS switch ON.
Turn the detector on and off using the LAMP ON/OFF key.
