Calibrating To A Known Thickness (Single Or 1 Point) - Cygnus 1 Ex Manual

be more accurate than using a 'general' velocity value. For calibration instructions
see page 42.
If there is no test sample available, the gauge can be calibrated by setting the
Velocity of Sound directly. A table on page 85 at the back of this manual lists
common materials and their velocity of sound value. For calibration instructions see
page 42.
A third method is to leave the Gauge set to its factory-pre-set value for Steel
[5920 m/s or 0.2332 in/us], and then use a Conversion Factor from Reading
Conversions on page 86.

Calibrating to a known thickness (Single or 1 Point)

This method of calibrating the gauge is more accurate than using a standard
velocity-of-sound value as the gauge calculates the velocity of sound for the
sample material.
You can use this calibration method in all measurement modes.
1. Accurately measure the thickness of
your sample material.
2. Place the Probe on the sample and
verify the gauge can get a stable
thickness value.
3. Access the Menu and scroll down to
the 'Calibration' group. Then scroll
right to the '1 Point Cal' item.
Press the √ key to open the '1 Point
Cal' function
