Evacuate the Internal Cylinder
If the content of the internal cylinder is unknown, or contaminated SF
6
gas is stored inside it, the
internal storage cylinder can be evacuated.
Press the Evacuate Internal Cylinder key in the Control
Setup menu.
The dialogue box requests you to remove the sampling
gas tube or connect an SF
6
reclaimer to the 973.
Disconnect the quick coupling from the SAMPLE GAS inlet
or connect the instrument to an SF
6
reclaimer.
Press the Ok button to start the internal cylinder evacua-
tion.
The dialogue box indicates the current internal cylinder
pressure during evacuation. After evacuating below 20 kPa
residual pressure, the internal pump automatically stops.
The evacuation process can be stopped by pressing the
Ok button.
If the 973 is connected to an external reclaimer, evacuation
can be continued with the reclaimer until the desired resid-
ual pressure is reached. By pressing the
Ok button, the
evacuation process can be stopped.
