    : Identifies the minimum thickness over a large area while moving the transducer over the CAN MODE surface. While the transducer is in contact with the material being measured the smallest value is held in memory and displayed when scanning is complete. : Allows the user to set a target so that an audible and visual alarm operates when taking LARM measurements.

  • Page 15: Taking A Reading

    4 TAKING A READING Disclaimer: Inherent in ultrasonic thickness measurement is the possibility that the instrument will use the second echo rather than the first echo from the back surface of the material being measured while in standard pulse-echo mode. This may result in a thickness reading which is TWICE what it should be. The responsibility for proper use of the instrument and recognition of these types of phenomenon rests solely with the user of the instrument.
  • Page 16 3. Read display If six or seven bars of the stability indicator are showing, the display will be reading the correct thickness of the material directly beneath the transducer. If the stability indicator has fewer than five bars showing, or the numbers on the display seem erratic, check to make sure that there is an adequate film of couplant beneath the transducer, and that the transducer is seated flat against the material.

  • Page 17: Calibration

    5 CALIBRATION 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 material have different sound-velocities. For example, the velocity of sound through steel is 5918 m/s (about 0.233 in/µs) and the velocity of sound through aluminium is 6350 m/s (about 0.248 in/ µs).
  • Page 18 5.1 KNOWN THICKNESS CALIBRATION This procedure requires a sample piece of the material to be measured, the exact thickness of which is known, e.g. from having been measured by some other means. 1. Switch on the gauge. 2. Apply couplant to the sample piece. 3.
  • Page 19 Note: At any time during the gauge calibration procedure (IN, MM, IN/µs, or M/s flashing in the display), pressing the SCAN key (207) or CLR key (207DL) will restore the gauge to the factory default sound-velocity for steel, 5918 m/s (0.233 in/µs).

  • Page 20: Set-Up Options

    6 SET-UP OPTIONS 6.1 MEASUREMENT MODE The gauge has three measurement modes; echo-echo, interface-echo and automatic. : The gauge has the ability to read thin metals from 0.15 mm to 10.14 mm (0.006" to 0.399"). ECHO The echo-echo mode also allows the user to measure the thickness of metals that have been previously coated or painted on the surface.

  • Page 40 15.1 INITIAL SIGNAL STRENGTH The stronger a signal is to begin with, the stronger its return echo will be. Initial signal strength is largely a factor of the size of the ultrasound emitter in the transducer. A large emitting area will send more energy into the material being measured than a small emitting area.

  • Page 41: Condition And Preparation Of Surfaces

    15.4 TEMPERATURE OF THE MATERIAL When it is necessary to measure on surfaces that are exceedingly hot, special high-temperature transducers may be necessary. Additionally, care must be taken when performing a ‘Calibration to Known Thickness’ with a high temperature application - see “Measuring hot surfaces” on page 40. 16 CONDITION AND PREPARATION OF SURFACES The shape and roughness of the test surface are of paramount importance when carrying out ultrasonic thickness testing.

  • Page 42: Application Notes

    17 APPLICATION NOTES 17.1 MEASURING TUBING When measuring a piece of tubing for wall thickness, it may prove beneficial to have multiple delay lines with different radiuses for different tubing diameters. The delay lines can be easily radiused by placing a piece of emery cloth around the tubing and moving the transducer back and forth until a radius has formed on the tip of the delay line.
  • Page 43 17.3 MEASURING LAMINATED MATERIALS The density (and therefore sound-velocity) of laminated materials may vary considerably from one piece to another. Some laminated materials may even exhibit noticeable changes in sound-velocity across a single surface. The only way to reliably measure such materials is by performing a calibration procedure on a sample piece of known thickness.
