f.s. (maximum display value or scale length)

The maximum displayable value or scale length. In this instrument, the maximum

layable value is the range (V/div) times the number of divisions (10) on the verti-

disp cal axis. Example: For the 1 V/div range, f.s. = 10 V

rdg. (reading or displayed value)

The value currently being measured and indicated on the measuring instrument.

dgt. (resolution)

The smallest displayable unit on a digital measuring instrument, i.e., the input value that causes the digital display to show a "1" as the least-significant digit.

Safety Information

This Memory HiCorder does not require a CF (CompactFlash) adapter. See "6.5 Data Management" (p. 88) for details about managing data storage in the card.

6.2 Using a CF Card

The following options are available for saving and loading measurement data with the Memory HiCorder.

• Format new CF cards before use.  To format with this instrument: (p. 76)

• Inserting a CF card upside down, backwards or in the wrong dire

ction may damage the CF card or instrument.

• Never eject a CF card while it ment. Data on the CF card could be lost.

• During battery-only operation, data may fail to be stored properly if bat

tery charge is exhausted while saving. In the worst case, the CF card could be damaged, so pay appropriate attention to the discharge state of the battery pack.

• If the Eject button is in the released position, press it in first before inserting the CF card all the way in. Inserting the CF card when the Eject button is released may damage the instrument.
