Dual-Multi Mode

Often times users and inspectors in the field are faced with coated materials such as pipes and tanks. Typically inspectors will need to remove the paint or coating prior to measuring, or allow for some fixed amount of error introduced by the paint or coating thickness and velocity. An A-Scan scope with a special echo-echo mode is generally used in order to accurately perform measurements through paints and coatings. However, In order to inspect for blind wall pitting and internal flaws, both echo-echo (thru-paint / coatings), and pulse-echo (locate flaws & pits) modes are needed. Special high damped dual element transducers are also a must when performing inspections using both modes without an a- scan scope for verification. A highly damped transducer rings for a much shorter time, allowing the MMX-6DLto measure thinner material thicknesses in echo-echo mode. This same transducer is equally effective when used in pulse-echo mode, eliminating the need to use different transducers for each mode. The new MMX-6DLgives you all these features in a simple to use, one button toggle, digital thickness gauge. The following steps outline the procedure for setting up this feature:

Dual-Multi Mode

1)Press ON/OFF key to power up the MMX-6 DL.

2)Press MODE key to activate features and settings.

3)Press the UP or DOWN arrow keys to scroll to GAtE.

4)Press the SEND key to toggle between modes ( E-E,P-E).

5)Press the MODE key once again to return to measurement mode.
