3. Can I use the device
without
The device will continue working without a network connection and can store up to 300,000 readings in its
memory. Real-time readings are disp ayed on screen and you can access the data in the following ways:
(j) Movethe deviceto an areawhere there is a WiFiconnection which the device can connect to. Pressthe power
button onceto manually trigger data sync.After the sync completes, it is recommendedthat you take the device
