5.3 Periodic Checkup
5.3.1 Check of Liquid Leak Sensor
For detection of liquid leak, a liquid leak sensor is mounted.
However, if the sensor is contaminated, liquid leak might not be
detected properly. To prevent this, checkup and cleaning should
be carried out periodically. Before checkup, the instrument must
be connected to the maintenance software of CDS.

Check of Leak Sensor Activation
Drip water on the liquid leak sensor and check if "LAMP
OFF BY LEAKAGE" error is indicated on the maintenance
software of CDS.

NOTE:
When using the liquid leak sensor, follow the
instructions given below.
(a)
Before using a solvent, the leak sensor function
should be activated.
(b)
The leak sensor function of this detector may fail
to work for leak in a very small amount.
The function may also fail to work for a solvent
having a high volatility. Always check for liquid
leak so as to circumvent a serious situation even
when the leak sensor function is activated.
(c)
Before measurement, visually check for liquid
leak as a routine checkup.
(d)
Check the leak sensor for proper functioning as
a periodic checkup.
