9. Gently lift the PID lamp out of the sensor module by pulling up.
Cleaning The PID Electrode Panel
Place the PID electrode panel into isopropanol. It is highly recommended that an ultrasound bath to be
used to clean it for at least 15 minutes. Then dry the electrode panel thoroughly. Never touch the
electrodes with your hand.
Also use an isopropanol-soaked cotton swab to wipe off the lamp housing where it contacts the sensor
when the sensor is installed.
Turn over the Electrode Panel so that the pins point up and the sensor cavity is visible. Examine the
sensor electrodes for any corrosion, damage, or bending out of alignment. The metal sensor electrode
"fingers" should be flat and straight. If necessary, carefully bend the sensor fingers to ensure that they do
not touch the Teflon portions and that they are parallel to each other. Make sure that the nuts on the
sensor pins are snug but not overtight. If the sensor is corroded or otherwise damaged, it should be
replaced.
Cleaning The Lamp Housing Or Changing The Lamp
If the lamp does not turn on, the instrument will display an error message to indicate replacement of the
lamp may be required.
1. If the lamp is operational, clean the lamp window surface and the lamp housing by wiping it with
isopropanol using a cotton swab using 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 use water solutions to clean the lamp. Dry the lamp and the lamp housing thoroughly after
cleaning.
CAUTION: Never touch the window surface with the fingers or anything else that may leave a
film. Never use acetone or aqueous solutions.
2. If the lamp does not turn on, remove the lamp from the lamp housing. Insert the new lamp, avoiding
contact with the flat window surface.
