5-36 Troubleshooting the Instrument
• After 15,000 to 20,000 hours (max 20 000 hours).
• If the flow cannot be adjusted to the desired value.
• If the Pump makes considerably more noise than new Pumps.
After replacing the pump, perform a CO
2
calibration check as described in “CO2 Gas
Measurement Calibration Check” on page 4-16.
127( When replacing the pump in the M3015A Measurement Server Extension
(sidestream CO
), you should also replace the CO scrubber at the same time.

The cumulative time the infrared lamp in the M3015A Measurement Server Extension
(sidestream CO
) has been operating is shown. When replacing the infrared lamp, this
counter must be reset. A reset of the infrared lamp time must be confirmed.
The intensity of the Infrared Lamp gradually decreases over time. As a result, periodic
replacement is necessary.
Agilent Technologies recommends replacement of the Infrared Lamp as follows:
• After 15,000 to 20,000 hours ( max. 20 000 hours).
• If the Instrument exhibits a noticeably larger noise on the CO
2
wave.
• If the Instrument does not pass the accuracy test after calibration.
