Lamp Removal And Examination; Lamp Cleaning - ION CUB Instrument User Manual

Place the Electrode Stack onto a clean, flat surface, flat surface downwards. Carefully twist the
detection window end of the Lamp into the O ring around the well in the underside of the Electrode
Stack. The Lamp window should now sit flush within the Electrode Stack.
This procedure ensures that the Lamp is firmly held in the Electrode Stack with
the detection window level with the electrodes for consistent and reliable VOC
readings. Lamp placement by any other means is likely to give unreliable readings
because the O ring in the Electrode Stack becomes trapped between the window
face and the Electrode Stack.
Carefully align the Sensor Body over the Electrode Stack plus Lamp. Push the Sensor Body down to
secure the assembly - two clicks should be heard.
Carefully align/push the new MiniPID 2 Sensor Body (4) into the Instrument Body (6).
Then ensuring, the Filter Disc (2) and O Ring (3) are correctly positioned, screw the Sensor Cover (1)
back onto the Instrument Body (6). Do not over-tighten.
The instrument MUST now be re-calibrated.

Lamp Removal and Examination

The Cub is a sensitive detector. Internal components must be handled with
clean hands and clean tools. The Cub Lamp is fragile. Handle with great care.
Never touch the window and do not drop.
Following removal of the Electrode Stack as described previously, the Lamp may now be carefully
removed:
•
If the Lamp is held in the Electrode Stack, carefully pull it out of the O ring around the well in
the underside of the Electrode Stack.
•
If the Lamp is sitting in the Sensor Body - the Lamp can be gripped and lifted out or the
Sensor Body can be inverted and the Lamp tipped out.
Inspection of the Lamp may reveal a layer of contamination on the detection window. This appears
as a 'blue hue.' To check for this, hold the Lamp in front of a light source and look across the window
surface at an angle.
If necessary clean the Lamp.

Lamp Cleaning

Clean the window using the PID Lamp Cleaning Kit supplied.
THE CLEANING COMPOUND CONTAINS ALUMINIUM OXIDE AS A VERY FINE
POWER. THIS MAY CAUSE IRRITATION OF RESPIRATORY TRACT AND EYES.
