12. properly seated the inlet cap is not tight or the pump has failed CLEANING AND REPLACING THE PID LAMP The function of the PID s detector is dependent upon exposure of the gas sample to UV light via a precision lamp A critical component of this lamp is its wavelength filter or window This window is the portion of the lamp directly exposed to the gas sample and is therefore potentially exposed to water vapor dirt debris and oil residues Because this lamp is used as a UV light source it is critical to understand that degradation of the lamp s output will cause the detector to lose sensitivity and in extreme cases can limit the range of the detector In order to retain peak performance of the VX500 PID detector it is vital that the unit s UV lamp window remain free of dirt debris and oil residues When the window is contaminated you must periodically remove these contaminants Refer to Figure 1 detailing the lamp s window The first step to preventing or decreasing lamp window contamination is repetitive replacement of the VX500 s sampling filter part number 17058157 Also be careful when storing a spare lamp to avoid finger contact with the window and do not attempt to clean the lamp with compressed air unless air source is oil and contaminant free It is virtually impossible to prevent all factors that obstruct or degrade the UV lamp s window surface therefore as a recommendation a 10 6 eV lamp should be cleaned after every
