7.2 Troubleshooting
When all the basic check items listed on the previous page are OK, take a corrective
action on the list below. If the same problem still remains after that, or a problem
other than the ones described below happens, contact Shimadzu's service engineer.
The Vacuum does not become OK.
It is suspected that the mounting of the O-ring
around the condenser lens is not correct, or the
pump oil of the vacuum pump is contaminated,
resulting in the deterioration of the exhaust ability.
Referring to "5.7 Replacing pump oil” and “5.5
Cleaning the condenser lens", carry out the
maintenance and inspection of the vacuum pump
and condenser lens.
Temperature of the spectrometer is
unstable, or does not reach the set
temperature.
It is suspected that the room temperature is not
normal, or the fan which supplies the hot air has a
problem. Check that the room temperature is
within 10 - 28°C and reset the AIRCON switch on
the switch panel.
Analysis accuracy is poor.
It is suspected that the argon gas leaks during
analysis or contaminant is deposited on the
electrode. Check if the sample is set correctly, and
carry out an analysis again. If the analysis
accuracy is not recovered even after that, refer to
"5.3 Maintaining the spark stand" to "5.6 Adjusting
the control gap" to carry out maintenance.
The buzzer on the temperature
indicator sounds. (It sounds when the
temperature inside the spectrometer
exceeds 42°C.)
It is suspected that the room temperature is not
normal, or the temperature controller has a
problem. Check that the room temperature is
within 10 - 28°C. Turn OFF the AIRCON switch on
the switch panel. Wait until the temperature
reading goes down to the room temperature, and
turn ON the AIRCON switch again.
