Logger Lite makes default calibrations available for all common units for supported sensors. Most of these sensors are Smart Sensors - the sensor has a memory chip which stores the calibration. When the sensor is connected, Logger Lite reads the calibration from the sensor.
There are a couple ways to get to the calibration storage dialog:
Selecting Set Sensor Calibration causes the current calibration to be written to memory on the sensor itself. You should only perform this action if you are absolutely sure that your current calibration needs to be available to all users of the sensor.
This action will restore the factory-default settings to the memory chip in a Smart Sensor. Sensors with switches (such as the Conductivity sensor) will only have defaults restored for the current sensor switch setting; alternate switch settings have distinct calibrations and will have to be restored separately.
A number of sensors, such as Dual-Force Sensors and Light Sensors, have switch settings with their own calibration. If you choose to write the defaults to one of these sensors, you will be prompted to select which setting you wish to restore. Make certain the setting on the sensor matches that in the dialog.
When an experiment file is opened, the desired units are obtained from the experiment file. Logger Lite will look for a calibration with the desired units in the location specified by the Calibration Retrieval Preference.
