This setting affects only the NanoTrak screen and not the main 'Settings' display.
If 'Microns' is selected and no piezo actuators are connected, the system sets
automatically the increment size to be the micron equivalent of 1 NT unit, e.g. for
a 20µm piezo travel, the increment would be set to 2µm.
To indicate that 'Microns' is selected and no piezo is connected, the data
displayed at the bottom of the NanoTrak screen is set to zero.
TIA tab
This panel is used to modify the autoranging and output characteristics of the
NanoTrak input amplifier circuit (Trans-impedance amplifier (TIA) circuit).
Input Signal Amplifier (TIA) Autoranging Settings
Auto-ranging Mode - when auto-ranging mode is selected on the GUI panel, range
changes occur whenever the input signal reaches the upper or lower end of the
currently set range.
This parameter specifies how these range changes are implemented by the system.
