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”
on page 119).
– To stop a scan in progress, press and hold the Scan (Measure) key.
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).
