When the MMX-6 is not in calibration mode, press the UP arrow key to
turn Scan Mode on and off. A brief message will appear in the display
confirming the operation. When the transducer is removed from the
material being scanned, the MMX-6 will (after a brief pause) display the
smallest measurement it found.
Alarm Mode
The Alarm Mode feature of the MMX-6 allows the user to set an audible
and visual parameter when taking measurements. When the Alarm Mode
is on, the green LED is illuminated. If a measurement falls below a nominal
value, set by the user, the red LED will illuminate and the beeper will
sound, if enabled. This improves the speed and effic iency of the inspection
process by eliminating constant viewing of the actual reading displayed.
The following pages outline how to enable and set up this feature:
Using the Beeper
1) While the unit is off, press and hold down the ALRM key.
2) Press ON/OFF key to power up the unit.
3) Release the ALRM key - BEEP ON or BEEP OFF will be displayed
enabling or disabling the beeper.
4) Repeat steps 1 through 3 to toggle between BEEP ON or BEEP
OFF.
