Page 29: Maintenance
MAINTENANCE Cleaning the Optical System Integrale The Kahn Series 4000 is a precision optical dewpoint hygrometer, which uses a four component optical system to detect condensation of water from a gas sample. This system comprises a light emitting diode (LED), two photo-detectors and a mirror surface. - Page 30 However, it is good practice to ensure the cleaning procedure is carried out regularly rather than waiting for the red ABC STATUS LED to illuminate.
