1. Read this first
Weighing sessions on an Optiweigh unit are a bit like yard weighing sessions - just longer. The point of having a session is to know which animals to group together to show a mob average and distribution.
We recommend that a new session be started every time the Optiweigh is put with a new mob of animals - or whenever the composition of the mob changes. The best way to think about it is to imagine the scenario of drafting some animals out of a mob: If a new session is started after drafting the averages and ADG calculations in the new session will only show the animals that are still in the mob.
Regardless of the sessions all the historical data for your animals is kept - and the weight chart and ADG calculations will include all the historical data from previous sessions - but only for animals that have been weighed in the current session.
2. Opening and Closing Sessions
To get any weight records you need to have an open session. When you click the button to start a new session the current open session will be closed at the same time.
The daily email will come through whenever you have an open session - so if you are not using your Optiweigh and do not wish it to keep coming simply go the list of open sessions and close the current open one.
