Using the Ultrasonic Thickness Gage 9-13
December 2003
Signal Inversion
This prompt enables you to invert the thickness transducer signal.
Signal inversion may be required if your thickness readings are
showing excessive jitter or for certain unusual combinations of
pipe and fluid or pipe and lining. Consult the factory before
measuring the thickness of lined pipes. Also, when measuring the
thickness of certain pipe materials (Teflon in particular), it may
be necessary to drain the pipe before measuring the pipe wall,
because certain pipe/liquid combinations muffle the ultrasonic
echo.
This option should be on unless otherwise instructed. To change
the signal inversion status:
• Press [F1] to turn the signal inversion ON or
• Press [F2] to turn the signal inversion OFF.
To exit the Thickness Gage Program Menu, press [EXIT].
