OPERATION MANUAL

4.2 – TROUBLESHOOTING
Prior to performing any troubleshooting measures, check all sources of power and pipe connections to ensure power and
process water supplies are being maintained to the analyzer.
CAUTION: Ensure that water is in the measurement chamber at all times during the operational cycle.
Insufficient water levels may result in damage to the system.
4.2.1 – Calibration Procedure
NOTE: The OIW analyzer is NOT calibrated to a National Standard. The analyzer is calibrated to the
laboratory results. Therefore references to calibration refer to the comparison using laboratory
results as the standard rather than a National Standard.
Analyzer measurements may not align with the Laboratory results which could be rectified by fine tuning the unit. The
OIW analyzer is fine tuned using laboratory based results as standard. Using specific oil types allows the system to be
calibrated for a unique oil type to provide measurements on site for every second the analyser is operational.
The following section will outline the Advanced Sensors recommended sampling and tuning procedures in addition to
describing gain adjustments to align the readings. Offsets are factory pre-set and shall only be adjusted by Advanced
Sensors trained personnel.
4.2.1.1 – Sampling Procedure
The following points should be observed to ensure samples sent to the Laboratory are consistent with the OIW Analyzer
measurement reading:
Sample extraction from the sample point shall be during the FLOW cycle.
The sample point, when the analyzer is not fitted with one, shall be fitted adjacent to the outlet of the analyzer
within 1 m of the unit.
When sampling for a calibration a minimum of 4-5 samples should be taken over a 12 hour period. Each
sample shall be labelled with the exact time taken (from the analyzer clock), date and location if applicable.
Sampling Steps:
1. Flush the sample point for 20-30 seconds to remove any accumulated debris from the pipe work.
2. Extract the sample over a of 30-60 second period during the FLOW phase of the cycle.
3. Record the measurement reading (averaged over the sample period if possible) along with the START and STOP
times of the sample extraction on the container or in a log. Use the clock on the OIW software for times
allowing the time to be traced in the SysLogs.
4. Once all samples have been taken, obtain the average reading (i.e. ppm) value for the extraction period using
the SamTrack utility software (see the Data Logging Handbook OIW-HBO-0003-EX-002 for additional
information).
NOTE: START and STOP times shall be taken from the OIW Analyzer clock only.
