3.Press F2 (MEM).
4.A screen will appear showing the approximate amount of available memory and the amount of memory already used. The bar graph is a rough indicator of remaining memory capacity as a percentage of total capacity.

A record contains a header and one or more data points. To estimate the approximate number of data points and records (logging runs) that can be stored with the available memory ...
1.Allocate 33 bytes for each header. A separate header is used for each record.
2.Allocate 7 bytes for each data point from Mode 1 and Mode 3 logging.
3.Allocate 14 bytes for each for each spatially averaged data point from Mode 2 logging. More memory is used in this mode because both average and peak values are stored.
4.Determine whether there is sufficient available memory to perform the desired task. If there is, proceed with logging as described above.
5.If you determine that there is insufficient memory to perform the desired task because much of the meter’s memory has been used, it will be necessary to empty the memory. Press F4 (QUIT)
6.To download the current memory contents, you must connect the 8718B to a computer. See Chapter 18, User's Software.
