Tinytag data loggers can be returned to Gemini Data Loggers using our product returns booking form.

We recommend that data integrity features are disabled before a data logger is returned to Gemini Data Loggers. This helps to ensure that your Tinytag DI system remains secure by recording that the data logger has left your closed system.

If data integrity features remain enabled on a data logger when it returns for calibration, this feature will be disabled during the calibration process and your data logger will return to you with data integrity features disabled.

We also advise that users download and save any data that remains on the data logger before it is returned for calibration. Any data that is left on a data logger prior to calibration will be lost during the calibration process.
