Settings File; Start Calibration - Gecko Compact Product User Manual

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.
You can also return all settings to factory default values by selecting the last menu item.
Please ensure you have a copy of the user-settings.dat text file to use as a reference before
returning the settings to factory defaults.

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 the
sensor to settle after the test circuitry is switched on before the 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.
