Page 15: 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 16: 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 (Through Coating mode), there is no need to remove the paint to take a measurement. -
Page 17: Echo-Echo Mode (Ee) (Mode 3)
Cygnus 2+ Operating Manual M5-CYG2P-M-01_Iss6.doc Single echo measurements use a twin element (twin element) probe, because there are two elements angled to a focal point there is a v-path error introduced. However this v-path error is mostly corrected by the gauge, and furthermore by performing a two point calibration. -

Cygnus 2+ Operating Manual M5-CYG2P-M-01_Iss6.doc Battery Life The gauge will operate continuously for approximately 10 hrs when fitted with Duracell Alkaline 1500 mA/hr batteries. Battery Level When not displaying a thickness measurement the display shows a battery level gauge. Note. The battery level gauge moves slowly up and down the display to avoid display “burn in”. -
Page 29: Calibration
Cygnus 2+ Operating Manual M5-CYG2P-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 49: General Points On Thickness Gauging
Cygnus 2+ Operating Manual M5-CYG2P-M-01_Iss6.doc 8. 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 50: Troubleshooting
Cygnus 2+ Operating Manual M5-CYG2P-M-01_Iss6.doc 9. 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 51 Cygnus 2+ Operating Manual M5-CYG2P-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 52: Updating Your Gauge
Before updating your gauge note the model and serial number of the gauge (see Turning the Gauge On on page Error! Bookmark not defined.). 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 53: Care And Servicing
Storage Do not store the Gauge in temperatures greater than 35˚C (95˚F). 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. -
