Overview - Elcometer 456 Guide D'utilisation

1 OVERVIEW

Elcometer 456 Scan Probes have been specifically designed for use
with the "Scan" and "Auto Repeat" modes on Elcometer 456 Model T
separate gauges. They are supplied with a highly durable 'snap on',
user replaceable, probe cap - allowing users to take individual
readings or rapidly scan large surface areas without damaging the
probe or the coating.
Scan Mode: When Scan Mode is selected,
users can slide the Scan Probe over the
entire surface area. As the probe is lifted
off the surface the gauge displays the
average coating thickness value (x)
together with the highest (Hi) and lowest
(Lo) thickness values. Each set of three
readings can be displayed on a run graph
and stored into the memory. This is ideal for
on line inspection.
Auto Repeat Mode: When the probe is
placed onto the coated substrate in Auto
Repeat Mode, the gauge automatically
takes readings at a rate of 140 per minute
until the probe is removed from the
substrate. Each individual reading is
stored into the memory. The Auto Repeat
Mode can be used to significantly speed
up the inspection of large coated areas
such as steel I-beams (RSJ's), tanks, ship
hulls, etc.
Note: "Scan Mode with Hold" allows the probe to be lifted off the surface for a
maximum of 1.5 seconds and replaced without starting a new set of readings -
allowing the user to avoid holes, weld seams, etc. in the substrate without
affecting the measurement results.
