Setting the Zero Point of the MX-1 is important for the same reason that
setting the zero on a mechanical micrometer is important. If the gauge is
not "zeroed" correctly, all of the measurements the gauge makes will be in
error by some fixed number. When the MX-1 is "zeroed", this fixed error
value is measured and automatically corrected for in all subsequent
measurements. The MX-1 may be "zeroed" by performing the following
procedure:
1) Make sure the M X-1 is on.
2) Plug the transducer into the MX-1. Make sure that the connectors
are fully engaged. Check that the wearface of the transducer is
clean and free of any debris.
3) On the top of the MX-1, above the display, is the metal probe-disc.
Apply a single droplet of ultrasonic couplant to the face of this disc.
4) Press the transducer against the probe-disc, making sure that the
transducer sits flat against the surface of the probe-disc. The
display should show some thickness value, and the Stability
Indicator should have nearly all its bars illuminated.
5) While the transducer is firmly coupled to the probe-disc, press the
PRB-0 key on the keypad. The MX-1 will display "Prb0" while it is
calculating its zero point.
6) Remove the transducer from the probe-disc.
