  • Page 6: Important Notice

    The following important information must be read and understood by all users of Cygnus ultrasonic thickness gauges. The correct use of Cygnus ultrasonic thickness gauges requires identification of the correct equipment for the specific application coupled with an appropriately trained and qualified operator or technician.

  • Page 7: Introduction

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc 2. Introduction Cygnus 4 Thickness Gauge The Cygnus 4 Ultrasonic Thickness Gauge is a rugged, handheld, battery-powered instrument designed for high-reliability multiple echo thickness measurements in harsh environments using ultrasound. The gauge can be used with a choice of Ultrasonic Probes, selected to suit the material and thickness range to be measured.

  • Page 8: Cygnus Instruments

    Our philosophy is to work closely with each of our customers to provide a range of products specifically for each application. Cygnus Ultrasonic Thickness Gauges are designed to be simple to use and to withstand the harsh environments that they are intended for.

    Fitting the Batteries The gauge requires 3 x AA/LR6/UM3 Batteries. Cygnus supplies and recommends Duracell Alkaline batteries. The batteries are located behind a cover on the rear of gauge. The hand strap can be separated by a push-button buckle to gain access to the battery cover.

  • Page 11: Connecting The Probe

    This would not be covered by the warranty. Connecting the Probe The Cygnus probe lead uses a custom made cable that offers superior flexibility and resistance to oils and ultraviolet light. The cable will not stiffen after exposure to ultraviolet light.

  • Page 13: Selecting The Right Probe

    The performance of any thickness gauge, and its ability to get a reliable measurement depends on selecting the right ultrasonic probe for the application and conditions. Cygnus gauges are therefore offered with a selection of probes suitable for most thickness gauging applications.

  • Page 14: Measurement Modes Explained And Compared

    This method has been used in all Cygnus gauges since the late 1970s. Multiple echo mode will ignore surface coatings, there is no need to remove the paint to take a measurement.

  • Page 15: Single Element Probes And Protective Membranes

    • Foams • Composites Single Element Probes and Protective Membranes All Cygnus single element probes have a soft face and are therefore fitted with a Polyurethane Membrane which provides better contact on rough surfaces and protects the probe face from wear, prolonging the life of the probe.

    70°C (160°F). For measuring higher temperatures Teflon membranes are available and suitable for surface temperatures up to 150°C (300°F) with intermittent contact. Contact Cygnus instruments to order Teflon membranes. When measuring high temperatures limit the time the probe is in contact with the hot surface to less than 4 seconds and ensure the probe has sufficient time between measurements to cool down.

  • Page 27: Calibration

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc 6. Calibration Why should I Calibrate my Thickness Gauge? Ultrasonic thickness gauges measure time in order to measure the thickness of the material being tested. The rely on the principal that sound travels through a material at a constant velocity or speed.

  • Page 28: Calibration Options

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc Calibration Options The Gauge is supplied tested and calibrated. The Gauge will have been calibrated to measure thickness through steel (grade S355JO) with a velocity of sound of 5920 m/s. Either a 15mm or 1/2” Test Block is supplied with the kit so the Gauge can be quickly checked for correct operation.

  • Page 30: Setting The Velocity Of Sound

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc ‘1PC’ Indicator Setting the Velocity of Sound The gauge uses the Velocity of Sound value to calculate the material thickness value. It is therefore important the velocity value is set for the material being measured.

  • Page 35: Selecting The Probe Type

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc Selecting the Probe Type The Probe Type must be set to the probe connected to it. If the wrong probe is selected the gauge will not measure accurately if at all. The Probe Type is displayed is displayed at the top of the measurement screen in the status area.

  • Page 36: Automatic Probe Detection

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc Remember settings and calibration is saved with each probe type. So if you change the probe type you may find a setting has changed – this is normal. The reason settings are saved with each probe type is so you can swap probes during a survey without having to re- calibrate each time.

  • Page 37: Measurement Units

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc Measurement Units The Gauge can display thickness measurements in either Metric (mm) or Imperial (inch).

  • Page 47: General Points On Thickness Gauging

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc 9. General Points On Thickness Gauging On very rough surfaces and especially if both sides are badly corroded, it is often necessary to move the Probe around to locate a back wall reflector. Sometimes a slight rocking movement can help find reflectors which are otherwise impossible.

  • Page 48: Troubleshooting

    Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc 10. Troubleshooting The Gauge will not Switch On • Are the batteries exhausted? • Check the batteries are inserted correctly. Difficulty obtaining a Reading • Check that the Probe lead is properly connected to both Probe and Gauge.
  • Page 49 Cygnus 4 Operating Manual M5-CYG4-M-01_Iss6.doc • When measuring on very heavily corroded metal with single element probes the gauge uses more power searching for a multiple echo match – this can significantly reduce battery life. So if you are frequently measuring on very heavy corrosion consider using a twin element probe as this will require less power to get measurements.

  • Page 50: Updating Your Gauge

    Before updating your gauge note the model and serial number of the gauge (see Turning the Gauge On on page 21). You can then check on the Cygnus website if your gauge has the latest firmware version, and if not proceed to download the update software.

  • Page 51: Care And Servicing

    Do not store the Gauge for long periods in conditions of high humidity. Repairs There are no user serviceable parts inside the Gauge. Therefore all repair work should be carried out by Cygnus Instruments or by an Authorised Cygnus Service dealer.
