  • Page 44: Selecting Measurement Options

    Setting the Count Time The count time defines how long the gauge measures. Longer count times produce better measurement precision. Troxler recommends a count time of two minutes for most sample measurements. The 30 second count time should only be used when a quick measurement is required because the precision is not as good as the longer count times.
  • Page 45 To change the count time, press 1 at the Setup menu. The gauge displays: 1. 1 min 2. 2 min * 3. 3 min 4. 4 min 5. 30 sec Quick Rdg Select the desired count time using the corresponding number key.

  • Page 47 Setting the Automatic or Manual Depth Mode The Model 4540 gauge offers two depth modes: Automatic and Manual. In the Automatic mode, the gauge software determines the source rod depth automatically. In the Manual mode, the operator must enter the source rod depth at a gauge prompt whenever taking a measurement.

  • Page 50: Site Preparation

    Site Preparation Asphalt Surface Preparation It is possible, but usually not necessary, to take direct transmission readings on asphalt. Drilling a hole in asphalt can be difficult and may require the use of a proper drill (not the drill rod) if the asphalt has cooled and hardened. Under normal conditions, a backscatter reading provides an accurate measurement of asphalt density Prepare the site as follows.

  • Page 51: Figure 5. Drill Rod Positioning

    WARNING Under no circumstances should you use the source rod of the gauge to drill holes. This could result in breaking or damaging the source rod or providing inaccurate readings. 4. Wearing safety glasses (or other locally approved safety devices), step on the plate and hammer the drill rod at least 50 mm (2 in.) deeper than the desired test depth.

  • Page 52: Figure 6. Marking The Test Area

    5. Remove the drill rod by pulling straight up and twisting the extraction tool. Do not loosen the drill rod by tapping from side to side with a hammer. This will distort the hole or cause loose material to fall into the hole. 6.

  • Page 60 Recording the Standard Count Troxler recommends keeping a daily log of the density and background counts (see Appendix F for a sample log). To verify gauge stability, compare the daily standard count to a reliable reference as follows:  During the first four days of operation of a new or recalibrated gauge, compare the daily standard count to the factory-calibrated values.

  • Page 61: Taking Measurements

    Taking Measurements The Model 4540 uses a low-activity gamma-ray source and a highly efficient gamma-ray detector.

    Trench Offset Vertical structures such as the walls of a building, trench, or ditch often “echo” gamma photons back to the gauge, which may adversely affect density measurements. Trench offsets compensate for the influence of vertical structures on measurements. Use a trench offset if taking a measurement inside a trench or within 18 inches (45 cm) of a large vertical structure.
