Any measurement can be repeated by selecting that
measurement again from the Soft-Menu.
The system displays several measurements, but the
summary report retains only the last 3 measurements of
each type.
The 3 report page measurements can be averaged and the
average used in other calculations. This averaging selection
is made in the Set Up/Preset Program page 3. Average
activity on/off and average number (number of measurements
averaged) can be set to the user's preference. Other presets
on this page that affect OB measurements for the European
method are Add 1 week to EDD and Display EDD with GA
value.
If results are displayed as question marks, the
measurement is not within the table range.
