For Level 1 cleaning, any data that is recorded when the sonde is out of water should be re-coded to NA (i.e. site visits), with the OG data kept only in Level 0 datasets. This flagging step should also happen across all data (aka, earlier in the workflow) so that you don't have to run this step for every site and every parameter.
