3.18.4 Leak Rate Measurement – Manual 1-Stage Mode
Note:
The Manual 1-Stage Mode can only be selected if operating in the
Expanded Menu Mode. Refer to Section 3.8.
1. If not already done, place the instrument into its Manual 1-Stage
mode. Refer to Section 3.14.2.2 Manual 1-Stage Mode .
2. Choose an attachment that will ensure the complete capture of the
gas leak. Connect this attachment to the end of the Hi Flow
Sampler’s main sampling hose and position the attachment’s inlet
over the leak source.
3. Position the inlet of the instrument’s background gas sampling hose
opposite the leak source, such that the leak source will not
contribute to the background measurement.
4. Begin the measurement process by selecting Start from the Main
Screen.

6. Begin measuring until a stable leak measurement is achieved—this
may take several minutes.
If desired, the flow rate can be manually controlled by using the
Speed function. Each press of the
I/O

key will lower the flow rate as
indicated by the speed bar moving to the left.
