GAIN
Note:
will only be displayed as a top level menu item if a dual element style transducer has
been connected, and the gauge is in either pulse-echo mode (P-E) or pulse-echo coating mode
(PECT). Multiple echo modes, which include both single and dual style probes, are equipped with
automatic gain control that optimises the gain setting automatically and in these modes,
disabled and not displayed.
Your gauge has been optimised for a medium gain setting and for the majority of applications it can
be used at this setting. Some applications however may require lower or higher gain settings:
•
Lower values might be necessary for noisy or granular cast materials. If the reading becomes
sporadic and will not settle down or resolve on a thickness value, it is reasonable to assume
that the material is either very noisy aluminium, or granular cast iron. In this instance, reduce
the gain to see if the reading settles down and becomes stable.
•
Higher values may be necessary when trying to measure a material that is hard to penetrate
(due to the material type, or the overall thickness of the material) and when locating fine pits or
flaws. In these instances, increase the gain to see if the reading settles down and becomes
stable.
To select a gain setting:
Use the control button to select
required from the submenu items:
• VLOW
• LOW
• MED
• HIGH
• VHIGH
10.2 UNITS
The measurement readings can be displayed in metric units (mm) or English units (inches):
Use the control button to select
setting from the submenu items:
• IN
• MM
