HP WaterSkis E1312A manual FETCh?, Example Transferring Stored Readings to Output Buffer

	FETCh?
	The FETCh? command retrieves measurements stored in the module’s internal
	memory by the most recent INITiate command and places them in the output buffer.
	This command is most commonly used with CONFigure.
Subsystem Syntax	FETCh?
Comments
	Execute INITiate before sending the FETCh? command to place the multimeter in the
	wait-for-trigger state. If the multimeter has not taken any data (i.e., if INITiate has
	not been executed), or if settings have been altered since the last FETCh? (i.e.,
	changing function or range), the “Data corrupt or stale” error will be generated.
Note	If you do not alter settings, you could “ FETCh?” the same data over and over again
	without error.

• Readings sent to the output buffer can consist of two different lengths (bytes or characters) in Real ASCII format:

±1.23456E±12 LF or

±1.234567E±12 LF

• Each measurement is terminated with a Line Feed (LF). The HP-IB End-or-Identify (EOI) signal is sent with the last byte transferred. If multiple measurements are returned, the measurements are separated by commas and EOI is sent only with the last byte. For example:

±1.23456E±12 LF,±1.234567E±12 LF,±1.23456E±12 LF EOI

• The Multimeter’s internal memory stores 512 readings maximum.

• Related Commands: CONFigure, INITiate, READ?

• *RST Condition: Executing FETCh? after a *RST generates error “Data corrupt or stale” ( *RST places the multimeter in the idle state).
