4.1 FRONT PANEL LIGHTS
Green light illuminates when:
• The alarm mode is active, and
• the measured thickness is greater than the alarm value.
Red light illuminates when:
• The alarm mode is active, and
• the measured thickness is less than the alarm value.
5 MEASUREMENT MODES
Your gauge has two measurement modes, Pulse-Echo and Echo-Echo.
5.1 PULSE-ECHO MODE (P-E)
This mode measures from the initial pulse (sometimes referred to as an artificial zero) to the first echo
(reflection). This mode only requires one reflection and it is therefore the most sensitive mode for measuring
weak reflections (flaws) typically found when measuring heavily corroded metals. If this mode is used to
measure a coated sample, then the thickness of the substrate plus coating will be measured.
Note: Rough surface conditions can have an effect on the overall accuracy in this mode. If the surface
condition is in question, the pulse-echo mode should be used in conjunction with performing an off block
automatic zero as the temperature gradient changes.
