PZX-7 DL Ultrasonic Thickness Gauge

2.3 CAL Key

The CAL key is used to enter and exit the PZX-7 DL's calibration mode. This mode
is used to adjust the sound velocity value that the PZX-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. This
provides increased linearity between transducers. Refer to page 16 for an
explanation on the various calibration options.

2.4 DATA Key

The DATA key accesses the data logging section of the PZX-7 DL, which consists of
50 sequential (single column) files with 250 storage locations per file. Refer to page
42 for an explanation on the various calibration options.

2.5 CLR Key

The CLR key is used in conjunction with the data logging section to clear a single
stored memory location. Refer to page 42 for an explanation on the various
calibration options.
2.6 +/- Increment/Decrement Key's
The +/- Keys are used to increment/decrement values, navigate menus, select menu
options, and navigate data files and storage locations.

2.7 MODE Key

The MODE key toggles the measurement modes. If a delay line transducer (dLY) is
selected from the PROB menu option, echo-echo (E-E) and interface-echo (I-E)
modes will be toggled. If a contact transducer (Con) is selected, pulse-echo (P-E)
and echo-echo (E-E) modes will be toggled. Finally, if the plastic transducer (PLAS)
option is selected, the thickness options thin (thin) and thick (thK) will be toggled. The
measurement modes and transducer styles offer the flexibility to address specific
application scenarios. Refer to page 11 for an explanation on the various calibration
options.
