1. Turn off UltraRAE power.
2. Open the bar code (tube) reader cover by unscrewing the
four case screws from the front of the monitor case.
3. Remove the sensor module from the lamp housing by gently
pulling on the module.
Note the sensor is made of Teflon and stainless steel material.
4. Dip the entire PID sensor module into GC grade methanol.
It is highly recommended that an ultrasound bath to be used
to clean the sensor for at least 15 minutes. Then dry the
sensor thoroughly.
5. If the lamp is operational, use a cotton swab to clean the flat
window surface with GC grade methanol. If the lamp does
not turn on, remove the UV lamp from the lamp housing.

surface.
7. Reinstall the PID sensor module.
8. Replace the bar code (tube) reader and tighten the four

Lamp Window Cleaning Procedure:
Clean the lamp window surface by wiping it with anhydrous
methanol using a cotton swab. Rub in a circular motion at
moderate pressure. After cleaning, hold the lamp up to the light
at an angle to detect any remaining film. Repeat the process
until the lamp window is clean.
Never touch the window surface with fingers or
anything that may leave a film. Never use acetone
on 11.7 eV lamps.
CAUTION: Water will degrade window surfaces,
especially the 11.7 eV lamp window.
