OPERATION
The MMX-6 interacts with the operator through the membrane keypad
and the LCD display. The functions of the various keys on the keypad are
detailed below, followed by an explanation of the display and its various
symbols.
The Keypad
This key is used to turn the MMX-6 on and off. When the gauge is
turned ON, it will first perform a brief display test by illuminating all of the
segments in the display. After one second, the gauge will display the
internal software version number. After displaying the version number, the
display will show "0.000" (or "0.00" if using metric units), indicating the
gauge is ready for use.
The MMX-6 is turned OFF by pressing the ON/OFF key. The gauge
has a special memory that retains all of its settings even when the power is
off. The gauge also features an auto-powerdown mode designed to
conserve battery life. If the gauge is idle for 5 minutes, it will turn itself off.
