Measuring Low Pressure
Measure low pressure in the range: -20 to 120 cmH
2
O. Never exceed an absolute
maximum of 5 psi (0.345 bar).
Refer to Figure 5-1 while following these steps:
1. Press R and follow on-screen instructions.
2. At the Analyzer, connect the Low-Pressure Adapter to the Flow/Low-Pressure Port.
3. Press L in the OTHER MEASUREMENTS or WAVEFORM SCREENS section.
4. Verify that the screen displays Low Pressure (Plo) or LPress. If the High-Pressure
Adapter is also connected, you may need to press L a second time.
5. Connect the Low-Pressure Adapter to the source.
6. Apply pressure.
7. Successively press G (Units) to select a pressure unit in the sequence: PSI Æ kPa
Æ Bar Æ mBar Æ ATM Æ inH2O Æ InHg Æ cmH2O Æ mmHg.
If the waveform is too small or too large, press F (Rescale) to view the waveform
within optimized limits.
