The IN/MM key is used to switch back and forth between English and
metric units. This key may be used at any time, whether the tool is
displaying a thickness (IN or MM) or a velocity value (IN/
µs or M/s).
The CAL key is used to enter and exit the PX-7 DL's calibration mode.
This mode is used to adjust the sound-velocity value that the PX-7 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 13 for an explanation of
the two CAL functions available.
The MODE key is used to toggle through the various features and
settings of the PX-7 DL ( alarm, diff, scan, gate, back light, and beeper ).
The MODE key is used in conjunction with the arrow and send keys to
enable/disable the features and settings. Refer to page 16 for a further
explanation of the different modes.
