4.4 Button Operation
4.4.1 Resolution Button
The resolution button toggles the behaviour of the OUTPUT control, between ‘Coarse’
and ‘Fine’ adjustment.
In ‘Coarse’ mode, one revolution of the pot varies the output by a factor of 10 greater
than in ‘Fine’ mode. In ‘Open loop’ mode, the full 150V range corresponds to about
12 turns of the pot in ‘Coarse’ mode.
4.4.2 Mode Button
The MODE button allows access to all the major configuration settings on the piezo
cube, allowing the user to limit the output voltage range to 75V, 100V or 150V; select
between open and closed loop operation; and adjust the display brightness. In
applications where the Piezo cube is being used in Closed loop mode in conjunction
with a Strain Gauge Reader cube (TSG001), the MODE button also allows the user
to select between 3 methods of routing the feedback signals.
The menu options are described in the following pages. To cycle through the menu
options, press the MODE button briefly (i.e. press for less than than 1 second).
To save (persist) a menu option, press and hold the MODE button for more than 1
second.
The current menu setting is indicated by a decimal point at the right hand side of the
display.
