Saving measurement data in the internal memory

Up to 100 (DO110) or 1000 (DO120) data items measured by the instrument can be
stored in the internal memory. Saving the measurement data is possible only when the
instrument is in the measurement mode.

1. Press the

key while the data to save is displayed.

The saved data is displayed for two seconds and then the display returns to the
previous screen automatically.

Note

If the data saved reaches 100 (DO110) or 1000 (DO120) data items, an error occurs and
"ERR No. 0010" is displayed. Copy or transfer necessary data to a PC and delete the data
from the memory ("Deleting all saved data" (page 36)).
