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.
3.
Reinstall the PID sensor module by pressing it into place with a soft, non-woven cloth. It
is not necessary to press excessively. When the Electrode Panel and Lamp Housing Cap
are replaced, the PID sensor will be properly seated.
4.
Inspect the two electrical contacts (pins) to make sure they are not pressed down.
5.
Replace the Electrode Panel.
Make sure the Electrode Panel is inserted with the correct side up. The bottom of the
Electrode Panel is larger than the top, and it fits into the top of the Sensor Module
directly over the PID Lamp Window (the word "UP" is imprinted on the top of the
Electrode Panel). If the Sensor Electrode Panel is upside down, it will not function
correctly and the cover for the Sensor Module cannot close completely.
