| Datalogging and Recording Functions: | |
| If the main unit is connected with your PC, weather data can be downloaded continuously and unlimitedly as long as your PC runs properly. | |
| If the main unit is disconnected with your PC, the main unit itself can capture a maximum of 200 sets of weather data. That means, the first data will be overwritten by no. 201 data. Also, the default option is 1 hour per weather data set and you can set the time interval manually. For example, 1 day per weather data set. | |
