Troubleshooting the Analyzer 5-5
NOTE
Achieve the final maximum lamp value in a clockwise direction only. This will
counteract any spring-bounce that might decrease the output level of the lamp
over time.
7. Once the value is maximized, tighten the securing screws ( 1 ) to lock the
lamp into position. Some minor drifting (less than 0.1 volts) is normal.
8. At the Utilities menu, select Analyzer Status and check the lamp intensity.
•
If the value is at least 120 but less than 255, the perox light source indicator,
although displayed in red, is acceptable for reporting results. Results will not
be flagged. Check the gains for the perox channel and continue normal
operation.
•
If the value is less than 119, select
Set Light Intensity
. Check the gains for
the Perox channel.
Reprogramming the Manual Barcode Reader
1. Locate the Codabar Settings in the Opticon User’s Manual.
2. Scan the Start (Z7) barcode with the wand. The barcode reader should be
emitting a constant beeping sound, which is an indication that it is in the
programming mode.
3. Scan the Do not transmit Start/Stop (F0) barcode. You should hear a single
high-pitched beep to indicate that the scanning was successful.
4. Scan the End (Z7) barcode label. A continuous beeping sound indicates that
the reprogramming is finished.
