When in ‘Scan Mode’ (PTG8 only) – see Section 9.3 Taking a Reading in Scan Mode’ on page en-20 – the reading rate is set at 16 Hz (16 readings per second). The gauges have a user-selectable reading resolution of 0.1mm (0.01″)- Low’, or 0.01mm (0.001″) – “High’, which gives more precise readings when measuring on thinner materials. To select the resolution, press Menu/Setup/Reading/Resolution and select ‘Low’ or ‘High’ as required.

SETTING LIMITS – PTG8
Limits are acceptable tolerance levels as defined by the user allowing the user to compare readings to pre-defined values. The PTG8 can store up to 40 pre-programmed limits. Limits can be created on the gauge or via PC using ElcoMaster”, and saved into the gauge memory for future selection. Using ElcoMaster”, saved limits can be transferred to other PTG8 gauges. Each Limit can consist of a nominal or target value (x:) required for ‘Readings & Differential – a low () and/ or high () limit value. Limits can either be created for individual readings or when a new batch is opened, see Sections 5.1 and 5.2. Different batches can have different limit values.

CALIBRATION METHODS

In order for the gauge to make accurate measurements, it must be set to the correct sound velocity for the material being measured. Different types of materials have different sound velocities. For example, the velocity of sound through steel is 5920m/s (approximately 0.233in/us) and the velocity of sound through aluminum is 6350m/s (approximately 0.248in/us). Setting the calibration is crucial for the gauge to function correctly. The calibration procedure should be performed when the measurement mode, transducer, and/or material type is changed. A choice of calibration methods is available, see Table 2: Calibration Methods. To select the calibration method, press Menu/Calibration/Cal Method.

For example:

• Number Of Rows =3,
• Number Of Columns = 3.
• Increment Direction = Across,
• The first reading will be saved in cell A1, the
• second A2, the third A3, the fourth B1, and so on.
• Increment Direction = Down,
• Number Of Rows = 3,
• Number Of Columns
• The first reading will be saved in cellA1, the second B1, the third C1, the fourth A2, and 3. So on.
• The batch settings are saved in the batch header and can be viewed at any time via Batch/Review Batch/Batch Information.

The batch settings are saved in the batch header and can be viewed at any time via Batoch/Review  Batch/Batch Information. The grid/ table is a template of the measurement area and where each reading is to be taken. If for any reason a reading cannot be taken in a particular location, due to a steel girder for example, the ‘Obst’ softkey can be used. When the transducer is removed from the surface, the ‘Save’ softkey changes to ‘Obst. Pressing Obst’ records that reading could not be taken.

Note: The number of readings within the batch includes those recorded as ‘Obst’ however, Obst’ readings are not included in statistics calculations.

20 APPENDIX 1: PREPARING THE TEST SURFACE

The shape and roughness of the test surface are of paramount importance when carrying out ultrasonic thickness testing. Rough, uneven surfaces may limit the penetration of ultrasound through the material and result in unstable, and therefore unreliable measurements. The surface being measured should be clean, and free of any small particles, rust or scale. The presence of such obstructions will gasoline avocado against  Often, a wire brush or scraper will be helpful in cleaning surfaces. In more extreme cases, a rotary sander or grinding wheels may be used, though care must be taken to prevent surface gouging, which will inhibit proper transducer coupling. Extremely rough surfaces, such as the pebble-like finish of some cast iron, will prove most difficult to measure. These kinds of surfaces act on the sound beam like frosted glass acts on light, the beam becomes diffused and scattered in all directions. In addition to posing obstacles to measurement, rough surfaces contribute to excessive wear of the transducer, particularly in situations where the transducer is ‘scrubbed’ along the suríace.
