2 Features and Functions
Front Panel Operation:
• To configure the measurement parameters and add a channel to the
scan list, use the Channel (Configure) key.
• To initiate a scan and store all readings in memory, press the
Scan (Measure) key. If you press the Scan (Measure) key with no
scan list defined, the instrument initiates a DMM- only measurement
(see “Stand-Alone DMM Mode” below).
• To stop a scan in progress, press and hold the Scan (Measure) key.
• To view the readings in memory, use the
View key (the readings are not
erased when you read them).
Remote Interface Operation:
• To define the list of channels to be included in the scan list, use the
ROUTe:SCAN command.
• To configure the measurement parameters on the desired channels,
use the
CONFigure and SENSe commands.
• To initiate a scan and store all readings in memory, use the
INITiate
or READ? command. Each time you initiate a new scan, the instrument
will clear the previous set of readings from memory.
• To stop a scan in progress, use the
ABORt command.
• To view the readings in memory, use the
FETCh? command
(the readings are not erased when you read them).
NOTE
You can use the READ? command in one of three forms depending on
which measurement mode you wish to use.
• If you omit the optional <ch_list> parameter and a scan list is not
currently defined, the READ? command applies to the internal DMM.
• If you omit the optional <ch_list> parameter and a scan list is
currently
defined, the READ? command performs a scan of the channels in the
scan list.
• If you specify a <ch_list>, regardless of whether a scan list is currently
defined, the READ? command performs a “temporary” scan of the
specified channels (independent of the present scan list).
NOTE
You can use the MEASure? command in one of two forms depending on
which measurement mode you wish to use.
• If you omit the optional <ch_list> parameter, the MEASure? command
applies to the internal DMM.
• If you specify a <ch_list>, the MEASure? command performs a
“temporary” scan of the specified channels (independent of the
present scan list).
