Storing readings in memory using the INITiate command is faster than sending
readings to the output buffer using the READ? command. The meter can store up
to 1024 readings in internal memory. If you configure the meter to take more than
1024 readings (using the sample count and trigger count), and then send INITiate,
a memory error is generated.
After you execute an INITiate command, no further commands are accepted until
the measurement sequence is completed. However, if you select TRIGger:SOURce
BUS, the meter will accept the *TRG command (bus trigger) or an IEEE-488 Group
Execute Trigger message. You can stop a measurement started with an INITiate
command by sending a device clear (see page 203)
CONFigure Example 3
The following program segment sets the state of two input channels and then
uses the ROUTe and READ? commands to take measurements on each. Channel 1
is set to the 10 Volt range with maximum resolution. Channel 2 is set to the 1 volt
range. Note that resolution is common to both channels, the NPLC in effect will be
the NPLC set by the last CONFigure command the meter receives.
