Settings File
You can save the configuration of your Gecko to a text file. Simply enter the "Settings File"
menu located at the bottom of the main menu.
Use the Right button to select the action. When saved, a file called "user-settings.dat" is
written to the top level folder of the SD card. Similarly, using the Load command will read in
this file and apply the settings contained therein. If a user-settings.dat file does not exist,
no settings will be changed.
Start Calibration
Some sensors include circuitry to test the response of the sensor components to a known
input signal. The Gecko can generate a signal (voltage step or sine wave) or simply initiate
the sensor's own calibration routine. If your 3D sensor has a calibration duration setting,
this menu item will be visible and initiated by pressing the Right button.
Once started, the raw ENZ channel values are shown in real time. The bottom line shows
that you can press Left to abort the calibration process, and also shows a countdown timer
describing the current stage of the process.
There are three stages to the process – the on-delay, the signal, and the off-delay. For step
calibrations, each stage runs for the "calibration duration" in the sensor setting. For sine
wave calibrations the delay periods are only a few seconds.
The start delay allows velocity sensors to settle after the test circuitry is switched on (which
can cause a small step response) before the calibration signal is applied, and the end delay
allows the sensor to respond to the signal being removed.
The sensor should not be disturbed during the test process. View the files in your
continuous data archive to see how the sensor responded compared to past tests.
