6 SET-UP OPTIONS
6.1 MEASUREMENT MODE
The gauge has three measurement modes; echo-echo, interface-echo and automatic.
E
CHO
-
ECHO
: The gauge has the ability to read thin metals from 0.15 mm to 10.14 mm (0.006" to 0.399").
The echo-echo mode also allows the user to measure the thickness of metals that have been previously
coated or painted on the surface. This enables the user to determine the thickness of the metal without
having to remove the paint.
I
NTERFACE
-
ECHO
: The gauge has the ability to read thicker metals from 1.65 mm to 25.4 mm (0.065" to 1.0"),
plastics and other difficult materials.
A
UTOMATIC
: In Automatic, the gauge will automatically switch between modes according to the different
materials being measured.
P
LAS
: Plas mode can be used to measure thin plastics using a special graphite tip - see “Spares” on
page 35.
The automatic (Auto) mode will generally be the mode of choice for the majority of common applications
with the following exceptions:
• The gauge should be set to echo-echo mode when through-coating measurements are required.
• The gauge should be set to interface-echo when plastics above 1.52 mm (0.060") are being
measured.
