Note: The gauge should be re-calibrated when the measurement mode is changed - see
Section 7 'Calibrating your Gauge' on page en-12. The calibration icon will flash
intermittently to indicate that re-calibration is required.
To select the measurement mode, press Menu/Setup/Reading/

TABLE 1: MEASUREMENT MODES
Icon Description
I-E 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
25.4mm (0.065" to 1") thick.
E-E Ideal for measuring thin materials, 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 0.15mm and 10.15mm
(0.006" to 0.4") thick.
PLAS Specifically used for measuring very thin plastics
between 0.15mm and 5mm (0.006" to 0.197")
thick. A graphite delay line is required when using
this mode, see Section 15.2 'Delay Lines' on
page en-26.
