H. Units: This combination of icons are illuminated in different sequences to
inform the user what measurement units are currently being displayed in the
small 7 segment area.
I. Small 14 Segment: Displays the current gain setting of the
PR-9
which will
always display medium (MED).
J. Units: This combination of icons are illuminated in different sequences to
inform the user what measurement units are currently being displayed in the
large 7 segment area.
K. Small 14 Segment: The material type is displayed in this area. If it is set to a
value of one of the materials in our material list, it will be displayed in alpha
characters indicating the material type. Otherwise it will be set to CUST,
indicating custom material type.
L. Features: The icons illuminated in this row across the bottom of the LCD
display which features are currently enabled. For a complete list refer to page
20. The
PR-9
can be locked once calibrated, to avoid accidently changing the
calibration. When this icon is illuminated, the
PR-9
is in lock mode. Refer to
page 21 for an explanation on locking the
PR-9
.
2.9 The Transducer
The Transducer is the “business end” of the
PR-9
. It transmits and receives
ultrasonic sound waves that the
PR-9
uses to calculate the thickness of the material
being measured. The transducer connects to the
PR-9
via the attached cable, and
two coaxial connectors. When using transducers manufactured by Dakota
Ultrasonics, the orientation of the dual coaxial connectors is not critical: either plug
may be fitted to either socket in the
PR-9
.
The transducer must be used correctly in order for the
PR-9
to produce accurate,
reliable measurements. Below is a short description of the transducer, followed by
instructions for its use.
