2.3 Sampling Hose and Attachment Connections
Connect the sampling hose to the instrument’s leak-gas inlet by clamping the hose to
the inlet as shown in Figure 2-2. Also connect the background gas sampling hose to the
unit’s BACKGROUND inlet.
Figure 2-2. Hose and Attachment Connections
The standard sampling hose is 6 foot long. If a longer length is needed, the optional 12
foot hose (P/N 0055-0287) can be ordered, or additional sections of hose can be added
by simply clamping them together along with connecting together the background-gas
hose.
Choose an attachment (refer to Section 2.5 Attachments) that will capture the entire
leak and attach it to the end of the hose.
2.4 Grounding
WARNING:
To prevent the possibility of a static discharge, the Hi Flow  Sampler should
be grounded while conducting a leak test.
Attach the unit’s grounding clamp to the nearest earth ground.
Tip:
When not in use, the grounding clamp can be stored by attaching it to one of the
shoulder straps.
