Perform a Low Pressure Analysis

  • Select the sample files for analysis for each port
  • Edit the penetrometer properties
  • Edit analysis conditions
  • Monitor analysis as data are collected
  Prior to starting an analysis, verify that the tank pressure for the gas regulator is at least 200 psig. Pressures less than 200 psig may cause inaccurate data or termination of analysis.

  1. Select Operation from the View drop down to enter or edit analysis information.
  2. Install a Penetrometer in a Low Pressure Port. Install a steel rod with cap detector in any low pressure port that does not contain a penetrometer. See Install a Penetrometer in a Low Pressure Port.
  3. For a selected port, click Browse and select a sample file or click New to create a sample file. If needed, change the Penetrometer mass and/or Sample mass field for the sample material being analyzed.
  4. Click Start to start the analysis. A window displays data as they are collected. A short delay is encountered before the port status at the bottom of the window changes from the Idle state. See Monitor a Low Pressure Analysis.
 
  • When the Start button is clicked, if any low pressure station does not show a cap detector reading that indicates the station has a penetrometer or rod and its cap detector in place, a warning message will be displayed and the analysis will not start.
  • When the next scheduled pressure is above atmospheric pressure and a cap detector and rod or pen is not in place, the same warning will be displayed and the analysis will be suspended until the operator has corrected the problem and resumed.
  • If a cap detector is removed when the pressure is above atmospheric pressure, the low pressure system will be vented to atmosphere and the analysis canceled, with an explanatory error message.
  1. When the analysis is complete, remove the penetrometer and store (or dispose of) the sample material as applicable. See Remove a Penetrometer from a Low Pressure Port.
