Operation

Turning the Gauge On

To turn the gauge on press the power X key once. After a short delay, a start-up
screen is displayed followed by the Cygnus logo. The gauge will then display a
measurement screen.

Turning the Gauge Off

To turn the gauge on press the power X key for 2 seconds until the "Shutdown
Gauge" message is displayed.

Taking Measurements

Taking ultrasonic thickness measurements is a straightforward process that first
requires making sure the surface is clean and prepared, applying an ultrasonic
couplant gel then placing the probe on the surface and observing the display for
the measurement.

Zeroing Twin Element Probes

When using a twin element probe you must perform a Probe Zero before you can
begin taking measurements. See Probe Zeroing (twin element probes) on page 49.
Perform a Probe Zero frequently, especially if conditions such as
temperature are changing. At least every 30 minutes.
1. Remove all scale, rust, dirt or loose coatings and
brush the test area clean.
