Install a Penetrometer in a Low Pressure Port

If fewer than four samples are to be analyzed, a steel rod with a receptacle for the cap detector must be installed in each unused low pressure port. The cap detector must see that a rod is installed.

 

If a penetrometer or blank rod is not installed in each port, vacuum conditions cannot be achieved and an analysis cannot be performed.

  1. Remove the capacitance detector from the low pressure port by turning it counter-clockwise and pulling forward. Place it on top of the analyzer or stand it on the surface next to the high pressure chamber.

  1. Turn the plastic cap counter-clockwise to remove.
  2. Turn the retaining knob counter-clockwise until it turns with little resistance.
  Do not remove the knob; internal components may become misaligned.
  1. If the low pressure port contains a blank rod, remove it. If it contains a penetrometer, see Remove a Penetrometer from a Low Pressure Port.
  2. If using a 3 cc penetrometer, install the spacer over the penetrometer stem. Insert the penetrometer stem into the port and push it in as far as it will go. The spacer is required for the 3 cc penetrometer only.

  1. Tighten the retaining knob by turning it clockwise until the penetrometer is firmly seated. Do not tighten with excessive force.
  2. Place the plastic cover over the penetrometer assembly and turn clockwise to tighten.
  1. Install the capacitance detector over the penetrometer and turn clockwise to tighten.
