3.1.3 Tilting the Instrument
The CPC is operated by using isopropyl alcohol which is absorbed into an alcohol cartridge.
If the instrument is tilted during operation, the alcohol will gradually seep out of the alcohol
cartridge. If this alcohol gets into the optical chamber, it may cause false particle counts and/or
damage to the optical system. This will temporary disable measurement, and in the worst case, it
will permanently affect the readings.
To avoid such problems, the CPC is equipped to generate an alarm, and stop the pump when the
instrument is tilted. In this case, a message 【PUMP STOP】 will be displayed. The alarm will go
off until the instrument is retuned to a horizontal position.
The pump will resume operation in 5 seconds after the instrument is returned to a horizontal
position. Then in approximately 10 seconds, the instrument will be ready for measurement.
Do not tilt the instrument up in a vertical position when observing the
display. If the instrument is tilted, there will be a beep sound, and the pump
will stop.
It is recommended that the instrument is placed on a substantially leveled
and stable surface.
