Troubleshooting
When the Letters / Figures on the KL-04 Controller Window
appear in Red
This indicates that the output of the laser diode of the particle sensor has fallen below the
specifi ed level. Correct measurement cannot be carried out under these conditions. If this
is encountered during the measurement operation, the “Sensor Degraded” warning message
appears after the completion of the measurement. If the red letters / fi gures on the “KL-04
Controller” window or the “Sensor Degraded” warning message appear often, the laser
diode may be damaged, or may have some problems. Please contact the supplier.
When the Letters / Figures are Displayed in Orange on the KL-04
Controller
This indicates a sample exceeding the specifi ed maximum particle number concentration,
or a sample mixed with air bubbles, or contamination, or condensation has occurred on
the particle detection fl ow cell area. If this is encountered during measurement, the “Bad
Sensing Condition” warning message appears after the completion of the measurement.
Perform “Noise Level Check and Flow Cell Cleaning” (see page 136) and “Cleaning Us-
ing a Cell Cleaning Brush” (see page 138) then remove any deposits and air bubbles in
the fl ow channel. If this problem persists even after repeated cleaning of the fl ow cell, the
fl ow cell or detection system may be damaged. Please contact the supplier.
When the Performance-Test Fails
When the Performance-Test fails, check that there are no problems with the Performance-
Test Parameters, the condition of the Test Particles, and no mistakes on the test, then repeat
the Performance-Test again.
If the failure persists even after several Performance-Tests, there may be problems with
the particle detector etc. Please contact the supplier.
