Figure 5-2. Accessing Low-Pressure Measurements
Measuring High Pressure
The Analyzer can measure high pressure from -2 to 100 psi. Be certain of your possible
source pressure before measuring high pressure. For example, normal bulkhead outlet
pressure could be too high. Unregulated cylinder pressure could also be too high.
Refer to Figure 5-3 while following these steps:
1. Press R and follow on-screen instructions.
2. At the Analyzer, connect the High-Pressure Adapter to the high-pressure port.
3. Press L in the OTHER MEASUREMENTS or WAVEFORM SCREENS section.
4. Verify that the screen displays High Pressure (Phi) or HPress. If the Low-Pressure
Adapter is also connected, you may need to press L a second time.
5. With the high-pressure source set to zero output, connect the High-Pressure Adapter
to the source. Note that various connection schemes are available.
6. Apply pressure.
7. Successively press G (Units) to select a pressure unit in the sequence: PSI Æ kPa
