Deleting the Recorded Files

You can delete the recorded data files using the keypad/display, or the

DELETE command on the serial line. The deletion is always done for all

data; you cannot delete individual files.

Note that the transmitter automatically overwrites the old data when the

memory is full, so manual deletion of the recorded files is not necessary

in normal use.

To delete the data files using the keypad/display:

1. Press any of the arrow buttons to open the Main Menu.

2. Select System by pressing the ► arrow button.

3. Select Clear graph memories by pressing the CLEAR button.

Press the YES button to confirm the selection.

CAUTION

This function clears the entire data history of the transmitter, including

all graphs and the content of the optional data logger module.

UNDELETE

Similarly to the DELETE command, the UNDELETE command is used

without any arguments. It will recover all deleted data that has not been

overwritten yet.
