The Auto Delete function is designed for cases when stored data
reaches the limit of the memory of the meter, which allows you to
choose whether to automatically overwrite the old data with the new
data. For example, the meter stores up to 200 sets of data. When the
user wants to store the 201
st
set of data and Auto Delete is checked,
the meter deletes the first set of data and stores the 201
st
data. If Auto
Delete is disabled, the new data will not be stored.
If the Auto Delete function is disabled, the meter will remind the user
to store new data when the meter runs out of memory
