Touchscreen Display
When the controller is first powered on, the display will be blank for a few seconds as the system
boots up. The first screen displayed is shown only briefly at startup and contains the Multimetrixs
logo controller model.
Powerup splash screen
Next, the main screen will be displayed. The top button labeled “SAMPLE” is used to turn on and
off the continuous display of the sensor raw magnitude and status information. When the button
is checked, the display will continually update. Unchecking this button will stop updating the
display and, in turn, allows more processing time available for the host serial connection.
