Probe Zero

Setting the Zero Point of the MMX-6 DL is important for the same reason that setting the zero on a mechanical micrometer is important. If the tool is not "zeroed" correctly, all of the measurements the tool makes will be in error by some fixed number. When the MMX-6 DL is "zeroed", this fixed error value is measured and automatically corrected for in all subsequent measurements. The MMX-6 DL may be "zeroed" as follows:

Performing a Probe-Zero

1)Make sure the MMX-6 DL is on.

2)Plug the transducer into the MMX-6 DL. Make sure that the connectors are fully engaged. Check that the wearface of the transducer is clean and free of any debris.

3)The metal probe-disc is on the top end of the MMX-6 DL. Apply a single droplet of ultrasonic couplant to the face of this disc.

4)Make sure that the MMX-6 DL is in P-E( pulse-echo mode ) by pressing the Dual-Multikey to toggle the modes.

Note: The Probe-Zero feature is not used in Echo-Echo Thru-Paint mode, and has been disabled. If the PRB-0key is pressed, while in this mode, “nO” followed by “Prb0” will be displayed.

5)Press the transducer against the probe-disc, making sure that the transducer sits flat against the surface. The display should show some thickness value, and the Stability Indicator should have nearly all its bars illuminated.
