Refer to
Basic Digital Multimeter (DMM) Operation
(on page 5-1) for more
details on DMM functions, attributes, and configurations.
Setting and querying channel attributes
You can view and edit channel attributes on the front panel using the channel
attributes menu. To access the channel attributes menu, press the
CONFIG
key
and then press the
CHAN
key. Use the navigation wheel and
CURSOR
keys to
change attribute values. Use the
ENTER
and
EXIT
keys to apply or cancel
settings.
With the exception of the DMM configuration attribute, you can view and edit
channel attributes using the remote command interface using the commands
residing in the channel logical instrument. For example, to set the label attribute
of a channel, use the
channel.setlabel
command; to retrieve the label
attribute of a channel, use the
channel.getlabel
query.
To set the DMM configuration attribute for a channel or group of channels, use
the
dmm.setconfig
command and specify the desired channels in the
<ch_list>
parameter. To retrieve the DMM configuration attribute for a
channel or group of channels, use the
dmm.getconfig
query.
For specific instructions on retrieving the relay closure count attribute, refer to
Relay closure count
(on page 4-22).
Closing and opening channels
Switching channels have specific settings for switch-only operations and specific
settings for switch with DMM operations. For switch-only operation, there are
three close methods and one open method. For switch with DMM operation,
there is one close and one open method.
The Series 3700 verifies the operation being requested for a channel is
supported by the specified channel and that the channel exists in the system.
NOTE
You can also scan, that is, perform a user-specified sequence of
close/open operations on multiple channels, for switch only
applications or the switch with DMM applications. Refer to Scanning in
the Series 3700 Reference Manual for information on scan operations.
