Troubleshooting RBC Clog and Flow Error Messages
1. Remove the front covers and observe the metering tube while a
cycle is in progress. Approximately 10–15 seconds after the start of
the cycle, the metering tube should be flushed of all liquid. Verify
that the liquid is completely flushed from the tube.
After the flush, a liquid column with a meniscus at the leading edge
should travel down the tube. Verify that the meniscus is visible at
the leading edge. A complete flush of the tube and a uniform
meniscus are important to correct metering.
2. Print the RUN Screen to record the metering times. The upper
metering time and the count time are both important in
troubleshooting clogs or flow errors.
3. Additional information pertaining to the last cycle can be found on
the RAW DATA SUMMARY Screen.
NOTE: The information is only available immediately after the
cycle is completed. Therefore, the screen should be printed
immediately after the clog or flow error occurs.
From the first DIAGNOSTICS MENU Screen, press [RAW
DATA SUMMARY] followed by [PRINT] to obtain a printout.
4. Information pertaining to the vacuum level in the Analyzer can be
found on the VOLTAGE READINGS Screen.
From the third DIAGNOSTICS MENU Screen, press
[VOLTAGE READINGS] followed by [PRINT] to obtain a
printout.
5. The metering times are automatically stored in the data log.
Configure the data log to display and print the upper metering time
and count time. (If necessary, refer to the directions given in
Chapter5, Operating Instructions.)
6. For a list of probable causes and corrective actions, refer to
Table10.3, Sample-Related Fault Conditions.
Troubleshooting the WBC Flow Error Message
1. The WBC FLOW ERROR message indicates a problem with the
kinetic rate of the WBC measurement. The kinetic information is
only available immediately after the cycle is complete. Therefore,
the screen should be printed immediately after the WBC flow error
occurs.
