change the self-purification time, and then press "Start" to start the self-purification. Note
that during the self-purification process, the barometric pressure source is still an external
compressed gas (tank). Do not disconnect the external compressed gas. In addition, if you
still need to continue to repeat the same compressed gas sampling, you can not directly
press "back" to start the next sampling.

Sterilization: The porous sampling head can be sterilized by autoclaving at 121
°
C

for 30 minutes (or wiped with 75% alcohol) at the high pressure steam sterilizer. The gas
dispersing head, the Petri dish and the appearance of the instrument are also used 75%
alcohol for wipe sterilization. After each sampling test, if you want to continue sampling
another compressed gas (cans), you need to repeat the sterilization treatment.

When installing the Petri dish, the dish must be stuck in the center of the base and the
bottom of the dish is pressed down to the base.

Pressing the "return" key before sampling is complete will forcibly terminate the
sampling operation. The internal airway solenoid valve will be automatically closed and
the sampling volume will be stopped, but the sampling record will be saved.

Catheter Interface: Gas duct interface with easy to plug can be replaced design, pull out
when you need to press the interface of the blue plastic ring, and then pull out the catheter,
and insert the catheter directly into the reverse pull the catheter To strengthen the blue
plastic ring sealing effect.
