Assuming the batteries are good the next thing to check is if the Probe Membrane is fitted correctly, has enough couplant behind it and is not damaged or worn. There are instruction on Probe Membrane care on the Cygnus Instruments website Technical Downloads page.
A correctly fitted membrane is essential for optimum gauge operation.
Gain Settings.
Some Cygnus gauges have a Gain Setting in their menu;
- If the Gain in too low then getting readings will be difficult or impossible
- If the Gain is too high then the gauge may display standing readings when the probe is not in contact with the material surface
To correctly set the Gain follow these simple steps;
- Make sure the probe face is clear of couplant and is not touching any surface
- Set the gain to a high value (i.e. 12)
- Observe the thickness display - If you see more than one flashing bar or a thickness value then reduce the gain by 1 and check the display again. Continue to reduce the gain untill you see one flashing bar on the display
- You now should have reduced the gain so the gauge is consistently displaying one flashing bar only
- The Gain has now been correctly set.
