1288 1288  
1678 +This feature allows you to configure the device to save its counting result to internal flash memory at specified intervals. By setting a save time, the device will periodically store the counting data to prevent loss in case of power failure. The save interval can be adjusted to suit your requirements, with a minimum value of 30 seconds.
