Measuring Low Flow
Measure low flow in the range: +/- 25 lpm. Never exceed
an absolute maximum of 35 lpm.
Refer to Figure 5 while following these steps:
1.
Press R and follow on-screen instructions.
2.
At the Analyzer, connect the Low-Flow Sensor to the
Flow/Low-Pressure Port.
3.
Press K (in OTHER MEASUREMENTS) or N
(in WAVEFORM SCREENS.)
4.
Connect the Low-Flow Sensor to the source.
5.
Apply flow.
6.
Successively press G (Units) to select a flow unit
in the sequence: LPM
Æ CFM Æ LPS Æ ml/min Æ
ml/sec.
If the waveform is too small or too large, press F
(Rescale) to view the waveform within optimized limits.
