Interface Echo
(IE) The total thickness from the top of any coating
through to the material density boundary (typically
the back-wall) is measured. Suitable for
measurement of materials between 1.65mm and
b
25.4mm (0.065" to 1") thick.
Echo-Echo
ThruPaint™
(EE) A coating of up to 2.0mm (0.08") thick is ignored
and the material thickness from the top surface of
the material to the material density boundary
(typically the back-wall) is measured. Suitable for
measurement of materials between 2.54mm and
b
25.4mm (0.100" to 1") thick.
Plastic
Mode (
) PLAS
PLAS Specifically used for measuring very thin plastics
b
between 0.15mm and 5mm (0.006" to 0.197")
thick. A graphite delay line is required when using
this mode, see Section 16.2 ‘Delay Lines’ on page
29.
b
Thickness range is dependent on the material being measured and the transducer used.
Note: The gauge should be re-calibrated when the measurement mode is changed -
see Section 7 ‘Calibrating your Gauge’ on page 13. The calibration icon will
flash intermittently to indicate that re-calibration is required.
