ClearView db Lamp Replacement Instructions

The operating lamp and its surrounding assembly are extremely hot to touch. Power the analyzer off and wait for the lamp assembly to cool before changing the bulb.

Do not touch the glass of the lamp as it may interfere with the output (Clean with alcohol if you accidentally do touch it).

1. Turn off power to the ClearView db analyzer.
2. Open the main enclosure.
3. The internal photometer box has a thumbscrew attachment on the lid. Loosen the thumbscrew to open the internal box lid.

4. Unplug the lamp wires.

5. When the lamp assembly has cooled enough to be comfortably handled, rotate the cam lock screws counterclockwise until the lamp is free. Pull the lamp from the block. 

6. Make sure the replacement lamp is clean. It may be cleaned with methyl alcohol or isopropyl alcohol and a cotton swab if necessary. Do not touch the lamp with bare fingers. Salt and oils from fingerprints will degrade performance.

7. Insert the replacement lamp over the pins by rotating the cam lock screws clockwise until tight. Insert the lamp power plug into the socket. Bend lamp wire down to avoid contacting the lid when closed.

8. Close the internal box and tighten the thumbscrew.

9. Close the enclosure and restore power. ClearView db will begin operation when the power is turned on.

10. Navigate to Menu > Diagnostic > Lamp (see screen) This screen shows typical values for lamp related diagnostics. Confirm you have more than 1,000,000 and less than 8,300,000 on Detector Counts and all parameters are OK.

11. Allow the new lamp to warm-up for 30minutes. After warm-up take a new reference (see reference procedure in manual).
