The PRB-0 key is used to "zero" the MX-5 DL in much the same way
that a mechanical micrometer is zeroed. If the tool is not zeroed correctly,
all of the measurements that the tool makes may be in error by some fixed
value. Refer to page 13 for an explanation of this important procedure.
The CAL key is used to enter and exit the MX-5 DL's calibration mode.
This mode is used to adjust the sound-velocity value that the M X-5 DL will
use when calculating thickness. The tool will either calculate the sound-
velocity from a sample of the material being measured, or allow a known
velocity value to be entered directly. Refer to page 14 for an explanation of
the two CAL functions available.
The MODE key is used to toggle through the various features and
settings of the MX-5 DL ( alarm mode, beeper, back light, units, scan
mode, and differential mode ). The MODE key is used in conjunction with
the arrow and send keys to enable/disable the features and settings.
