In normal operation, the MX-5 DL performs and displays four
measurements every second, which is quite adequate for single
measurements. In Scan Mode, however, the tool performs sixteen
measurements every second. While the transducer is in contact with the
material being measured, the MX-5 DL is keeping track of the lowest
measurement it finds. The transducer may be "scrubbed" across a surface,
and any brief interruptions in the signal will be ignored. When the
transducer loses contact with the surface for more than a second, the MX-5
DL will display the smallest measurement it found.
When the MX-5 DL is in measurement mode, press the MODE key to
activate the features and settings. The display will begin flashing ALAr
(alarm), followed by the status - on/off. Use the UP and DOWN arrow keys
to scroll to SCAn mode. Press the SEND key to toggle scan mode on/off.
While scanning, the display is updated faster than normal which may result
in flickering of the values displayed. When the transducer is removed from
the material being scanned, the MX-5 DL will (after a brief pause) display
the smallest measurement it found.
Alarm Mode
The Alarm Mode feature of the MX-5 DL allows the user to set an
audible and visual parameter when taking measurements. If the
measurement falls below a nominal value, set by the user, a red light will
be illuminated on the front panel of the gauge and the beeper sounded.
This improves the speed and efficiency of the inspection process by
eliminating constant viewing of the actual reading displayed. The following
procedures outline how to enable and set up this feature:
